Genetics Flashcards
Hereditary Disorders
disorders
are derived from one’s
parents, are transmitted
in the gametes through
generations and,
therefore, are familial
Congenital Disorders
implies present at birth
types of mutations
point
frameshift
trinucleotide repeat
point shift mutation
substitution
of a single nucleotide base by a
different base
frameshift mutation
insertion or deletion of one or two base pairs
TRINUCLEOTIDE REPEAT
MUTATIONS
amplification of a
sequence of three nucleotides
What structural variations may DNA undergo
amplification
deletion
translocation
structural changes to DNA result in
aberrant gain or loss of protein function
what is Philadelphia chromosome
translocation of T(9.22) between two genes in chronic myeloid leukemia
What are the 3 types of genetic disorders
mendelian
mutlifactoral inheritence
cytogenic
mendelian disorder
autosomal dominant, recessive, x-linked
caused by single gene defect
cytogenic disorders can be
autosomes, sex chromosome aberrations
