Albinism is a genetic condition characterized by little or no pigmentation in the skin, hair, and eyes. It is caused by an inability to produce the pigment melanin and affects people of all races. In Africa, people with albinism face additional dangers as there is a belief that their body parts can be used for witchcraft rituals, leading to increased risks of attack. They also have health problems like lung illness and bleeding from an inability to protect against the sun's UV rays.

Albinism
The document discusses a study on albinism in Puerto Rico. The study aims to determine the predominant type of albinism on the island and estimate the number of people affected. It will involve obtaining permissions, distributing surveys, and analyzing results to discover if the most common type with no pigment in skin, hair, and eyes predominates or if another type is more prevalent. The research also seeks to identify what areas of Puerto Rico have higher concentrations of people with albinism.
Acquired and Inherited Traits
Traits can be either acquired or inherited. Acquired traits are not heritable and result from external factors like injury or disease, while inherited traits like eye color, height, and disease susceptibility are passed down from parents through DNA. Some traits have both inherited and acquired aspects, such as skin color which is determined by both genes and sun exposure, and earlobe attachment and dimples which have genetic components.

People with Albinism in Tanzania
The document discusses research into best practices for reducing stigma towards people with albinism (PWA) in Tanzania. It finds that stigma reduction programs should educate communities, empower PWA, and utilize local leaders. Integrating PWA into mainstream society can help reduce "us vs them" thinking. While a few NGOs in Tanzania address these issues, more can be done to educate traditional healers, as they are respected community members who could influence beliefs. Overall, addressing stigma requires understanding local context and implementing multi-pronged, community-based approaches.

Albinism powerpoint[1]
Hermansky-Pudlak syndrome is a rare genetic disorder characterized by oculocutaneous albinism which causes abnormal pigmentation of the skin, hair and eyes. It is caused by mutations in genes responsible for producing protein complexes that construct lysosome-related organelles important for pigment production. The condition is inherited in an autosomal recessive pattern and causes fair skin/hair color, visual impairment, and increased risk of skin damage from sun exposure. Diagnosis involves examining physical features and genetic testing. While there is no cure, treatment focuses on protecting the skin and eyes from sun exposure.
Albinism. Some might wonder why this disorder doesnt phase out.pdf
Albinism is a genetic disorder characterized by little or no production of melanin pigment, resulting in pale skin, hair and eyes that are prone to sun damage. It occurs when both parents pass on a recessive gene causing a mutation in the tyrosinase enzyme needed to produce melanin. Differences in skin color between populations are an adaptation to varying levels of ultraviolet radiation exposure from the sun in different climates. People near the equator evolved darker skin containing more melanin to protect against strong UV rays, while those in colder climates developed lighter skin with less melanin since UV exposure is lower.
Albinism
Albinism is a genetic condition where people are born without the usual pigment (color) in their bodies. Their bodies aren't able to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair color. So most people with albinism have very pale skin, hair, and eyes.
Colour variation in humans
Humans originated in Africa with dark skin to protect against high UV radiation levels. As humans migrated to regions with lower UV levels, genetic mutations occurred leading to lighter skin tones that allowed more vitamin D production. Variations in melanin pigmentation across populations developed as an adaptation to local UV exposure levels and resulted in different skin, hair, and eye colors distributed globally according to UV maps. Today, genetic mutations continue to affect melanin levels and produce variations in human features.
Melanin--Synthesis-Rajendra
1) Melanin is the pigment that determines skin and hair color and is produced in melanocytes.
2) Types of melanin include eumelanin, pheomelanin, and neuromelanin, which impart different colors.
3) Albinism is a genetic condition that results in little to no production of melanin, causing lack of pigmentation in hair, skin, and eyes along with vision problems.
Albinism
Albinism is a genetic disorder characterized by little or no production of melanin pigment. This results in white hair, pale skin, and vision problems. There are two main types - oculocutaneous albinism, which affects the eyes, skin, and hair, and ocular albinism, which only affects the eyes. The types are distinguished by their genetic cause and symptoms. Albinism is inherited through autosomal recessive or X-linked inheritance patterns. Diagnosis involves examining family history, vision, skin pigmentation, and sometimes genetic testing. There is no cure, but treatments focus on managing vision problems and protecting the skin from sun exposure.
Albinism
Albinism is a genetic disorder characterized by little or no production of melanin pigment, resulting in pale skin, hair and eyes. It is caused by a recessive allele that prevents the production of tyrosinase, an enzyme needed to produce melanin from the amino acid tyrosine. There are two main types: oculocutaneous albinism affecting the eyes, skin and hair, and ocular albinism only affecting the eyes. Treatments include protective clothing, sunglasses and sunscreen to prevent sun damage.
Melanin
Melanin is a broad term for natural pigments found in most organisms. It is produced by melanocytes in the skin, eyes, ears and other areas from the amino acid tyrosine through a process involving the enzyme tyrosinase. There are three main types of melanin - eumelanin, pheomelanin, and neuromelanin - which impart different colors. Melanin functions to protect skin and other tissues from UV radiation damage by absorbing UV light. Genetic disorders can result in hyperpigmentation, hypopigmentation, or lack of melanin production as seen in vitiligo and albinism.
Albinism.pptx
Albinism is an inborn disorder characterized by a partial or complete lack of pigmentation in the skin, hair, and eyes. It is caused by an absence of the tyrosinase enzyme in melanocytes, which is required for synthesizing melanin pigment. Without this enzyme, people with albinism cannot produce melanin, resulting in white skin, hair, and irises. They are also more susceptible to sunburns, skin cancer, and photophobia due to the lack of protective melanin pigment. Albinism is an autosomal recessive genetic disorder.
Albinism
Albinism is a genetic disorder where melanocytes cannot produce enough melanin, resulting in a lack of color in hair, skin, and eyes. It is caused by a recessive gene, requiring both parents to carry the gene for a child to be affected. Albinism affects people of all races and can cause vision problems, skin problems, light sensitivity, and increased risk of skin cancer. Treatment focuses on protecting the skin from sun exposure and managing vision issues. Most people with albinism can expect a normal lifespan, though some related conditions may reduce life expectancy.
Albinism
Albinism is a genetic condition that causes little or no pigmentation in the skin, hair, and eyes. It results from a faulty gene that prevents the body from producing typical amounts of melanin. People with albinism often experience vision problems, sensitivity to light, and lack of color in their features. While albinism has been observed throughout history, it was not formally recognized as a genetic condition until 1908. Today, genetic testing can help diagnose different types of albinism, while treatments focus on protecting the skin and eyes from sunlight and correcting vision issues.

Albinism
This document discusses albinism, a congenital disorder characterized by little or no pigmentation in the skin, hair and eyes. It is caused by a recessive gene that results in a lack of the enzyme tyrosinase needed to produce melanin. There are different types of albinism that can affect the eyes only or eyes, skin and hair. Albinism is associated with vision defects like photophobia, nystagmus and astigmatism as well as sun sensitivity. Diagnosis involves genetic testing or eye exams. Treatment focuses on protecting the skin from sun exposure and addressing vision problems. The condition does not affect lifespan except in rare cases of associated disorders.
Skin Diversity Reflection
This document discusses skin diversity and phenotypic variation between and within human races. It notes that people of the same race can look completely different from one another due to variations in skin color, eye color, and other physical traits. These differences are caused by differing amounts of melanin pigment in skin and eyes. The document explores how the author's understanding of skin tones and their associations with different parts of the world has evolved over time and with exposure to more diverse populations.

Albanism
Albinism is caused by a point mutation that depends on the specific case. The most common form is oculocutaneous albinism, which has four types: OCA1, OCA2, OCA3, and OCA4. Symptoms include little to no pigment in hair, eyes, and skin, eye problems like poor vision, and sun sensitivity. Albinism does not improve or worsen over time, but increases risk of sun damage and skin cancer. Incidence is about 1 in 17,000 in the US but higher in some other areas, and about 1 in 70 Americans carries the gene. Albinism is inherited through recessive alleles, so a carrier can pass on the gene without having albinism

Albinism
Albinism is a genetic disorder that causes partial or complete lack of melanin pigment in the skin, hair and eyes. Melanin is responsible for skin, hair and eye color and protects against UV radiation. There are different types of albinism depending on whether the lack of melanin affects just the eyes or both eyes and skin. The most common types are oculocutaneous albinism, which affects eyes and skin, and ocular albinism, which only affects the eyes. Albinism is usually inherited in an autosomal recessive pattern and can cause vision problems, light sensitivity, and higher skin cancer risk. While there is no cure, treatments focus on vision rehabilitation and protection from UV exposure.
Albinism
Albinism is a hereditary condition caused by a lack of melanin pigment in the skin, hair, and eyes. It results from a recessive gene and causes little to no pigmentation, making skin and hair very light in color and eyes often red or blue. Symptoms include light sensitivity, vision problems, and nystagmus. There are different types of albinism that vary in severity based on the amount of residual melanin present. Proper sun protection and sunglasses are important to manage health issues associated with albinism.
Oculocutaneous Albinism & Cutaneous Malignant Tumors
Albinism is a genetically inherited disorder characterized by hypopigmentation of the skin, hair, and eyes due to a reduced or lack of cutaneous melanin pigment production. The mode of inheritance of albinism is thought to vary, depending on the type. The oculocutaneous type is considered autosomal recessive, and the ocular variant sex-linked. Oculocutaneous albinism exists in four forms. One form involves the tyrosinase gene (OCA1), whereas the other form (OCA2) has recently been associated with alterations of the P gene on chromosome 15. There are five types of OCA; of these OCA1 and OCA2 are by far the most frequent types. OCA type 1 (OCA1) occurs with a frequency of about 1/40000 worldwide. (SCC) carcinomas and malignant melanoma (MM)—and collectively they represent the commonest cancers of humans, with intense exposures (especially in early life) and chronic exposures being linked to MM and SCC/BCC, respectively. Globally, variation in skin pigmentation (measured by the proxy of reflectance) in indigenous populations correlates strongly with levels of UVR exposure quantified by satellite measurements, which in turn correlates strongly with latitude. As most persons with severe forms of OCA are very prone to sunburn, the progenitor basal cell keratinocytes of sun-exposed skin of albinos are at great risk of undergoing sunlight-induced malignant transformation. SCCS in albinos can arise de novo or from premalignant actinic lesions such as sunlight keratosis, in which the keratinocytes have already undergone a sunlight-induced initial transformation. Sunlight regularly causes these genetic alterations that are referred to as UVR-associated ―signature mutation and these signature mutations drive the malignant transformation of sunlight-induced SCCS [36, 38]. Initially transformed keratinocytes are immunogenic and thus generate immune responses which can modulate or control tumourigenesis, but sunlight-induced immunosuppression may critically interfere with this protective mechanism.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
