I allow, welcome, and be happy to learn and study my slides that I
upload here in my profile on Slide share website
There is also no objection to copying one or two slides when
necessary, and there is no objection to explaining my PowerPoint to
others on the condition that my name is not removed from the
PowerPoint. I never allow my name to be removed from PowerPoint
and to replace it with yours, Make it look like you designed it. This is
theft that I do not allow and a waste of the right of those who are
tired in this work. May God bless you and me for learning and
benefiting others

Types of mutations
1_ small mutation that affect single gene :
• A_ point mutation
• B_ Deletion
• C_ Insertion
2_ Large-scale mutation : It is abnormality in
• A_ chromosomal number
• B_ chromosomal structure
6
Point mutation
1- Silent mutation :
as UGU ➡ UGC all coded for Cysteine
‫اتغيرت‬

2- Non-Sense mutation :
as UGU coded for cysteine ➡ UGA coded for stop codon result in shorter protein
can't function at all
‫اتغيرت‬

‫فتوقف‬

.
Example:
a. CAG in exon 2 normally codes for glutamine.
C→T mutation turns it to stop codon (TAG) resulting in β0 thalassemia.
b. Non-sense mutation in exon 3 of β gene: leading to severe unstable beta chain
(dominant thalassemia phenotype).

Point mutation
3- Sense mutation :
as UGA coded for stop codon ➡ UGU coded for cysteine result in longer
protein can't function at all

Examples:
b. Hb Constant Spring: α chain of 172 amino acids instead of 141 (excess 31
amino acids).
4- Missense mutation :
as UGU coded for cysteine ➡ UAU coded for Tyrosine, it may be :

A_ abnormality in chromosomal number
• It's due to errors in gametes formation
aneuploidy Polyploidy
19
Aneuploidy
for example
• 1_ Turner syndrome ➡ 45,X or 45,X0).
• 2_ Klinefelter syndrome ➡ 47,XXY
• 3_Edwards S➡trisomy of chromosome
18.
• 4_ Down S ➡ trisomy of chromosome 21.
• 5_ Patau S➡ trisomy of chromosome 13.
• 6_ Trisomy 9.
20
Down Syndrome Turner syndrome
21
Polyploidy
1_ Triploidy : 3 set of
chromosome (3n) 69
chromosomes
2_ Tetraploidy : 4 set of
chromosomes (4n) 92
chromosomes
It is non compatible with life, if
occurs in cells the cell is
abnormal.
22
Triploidy
23
B_ Abnormality in chromosomal structure
It's due to errors in gametes formation or mutagenes ( physical,
biological).
•for example :
1_ Deletion ➡ as Cri du chat deletion syndrome, 1P36
2_ Duplication
3_ Inversion ➡ inv (3) ( q21;q34)
4_ translocation➡ Philadelphia Chromosome in CML
