This document summarizes several genetic disorders: Down's syndrome is characterized by an extra copy of chromosome 18 and features like upward slanting eyes. Edward's syndrome involves a missing part of chromosome 5 and a cat-like cry. Lejeune's syndrome only affects females who lack an X chromosome and have facial abnormalities and infertility. Turner's syndrome is caused by missing genetic material on the X chromosome and causes short stature. Williams-Beuren syndrome is due to a microdeletion on chromosome 7 and causes facial features and cardiovascular issues. Klinefelter's syndrome occurs only in males with two or more X chromosomes and causes infertility and gynecomastia. Tay-Sachs disease is a recessive disorder caused

1. GENETIC DISORDERS

2. v
This disease is characterized by
severe hypotonia. The facial
characteristics of upward sloping,
palpebral fissures, small ears and
protuding tongue.This disease is also
known as Trisomy 21.
DOWN’S SYNDROME

3. n
 A chromosomal abnormality characterized by the
presence of an extra copy of genetic material on the
18th chromosome, either in whole (trisomy 18) or in
part. The physical malformations associated with this
syndrome are micromegaly,malformed ears, upturned
nose , clenched hands etc.- Name it?
EDWARD’S SYNDROME

4. c
 This syndrome is known as chromosome 5p
deletion syndrome, 5p− (said minus)
syndrome. It is due to missing part of
chromosome 5.crying of child is similar to that
of meowing kitten. This is also known as cri-
du-chat syndrome. Symptoms associated with
this disease hypotonia, microcephaly, growth
retardation, a round face with full cheek.
LEJEUNE’S SYNDROME

5. .
 This genetic disorder affects only
females. They partially or completely
lack X chromosome. This disorder is
also 45 X. They show characteristic
facial disorder, webbed neck and they
are infertile and cannot bear a child.
 TURNER’S SYNDROME

6. .
 A genetic syndrome due to
microdeletion of chromosome 7.
hypercalcemia is seen from childhood.
They lack gene coding for elastin which
results in haploinsufficiency. They have
short stature and sloping shoulder.
WILLIAMS – BEUREN SYNDROME

7. .
 This syndrome occurs only in males.
They have two or more X
chromosomes. At adolescence, they
tend to be taller than average. They are
infertile. They have some degree of
gynecomastia.
 KLINEFELTER’S SYNDROME

8. .
 This is an autosomal recessive genetic
disorder. It is the accumulation of
Ganglioside in the brain. It is the
mutation in the HEXA gene present on
chromosome 15. It is also known as
Hexosaminidase A deficiency.
 TAY- SACH ‘S DISEASE

9. .
 An extra X chromose is present.
Affected women are unusally tall, have
epicanthal folds in eyes, microcephaly.
??
TRIPLE X SYNDROME

10. V
 It is a common disorder that affects the
connective tissue. This syndrome affect
eyes, connective tissue and
cardiovascular systems. They have long
arms and legs.
 MARFAN’S SYNDROME

11. .
 This rare syndrome affect the eye.
Affected individuals have problem in eye
sight, movement of eye ball.
 DUANE SYNDROME

12. .
 It is an inherited neurological disease. It
affects involuntary muscle. The affected
person lack a protein whose function is
unknown but vital. The disease is
named after the deficient protein.
HUNTINGTON’ SYNDROME

13.  This is a rapid aging disease.
 PROGERIA
