Specific Distribution of GJB2 Mutations in Kurdistan Province of Iran; Report of a Relatively Isolated Population

Hearing Loss (HL) represents high genetic heterogeneity with an incidence of almost 1 out of 500 newborns in most populations. Approximately half of the cases have a genetic basis that most of them are autosomal recessive non-syndromic (ARNSHL) with DFNB1-related defect in many worldwide populations. Given the heterogeneity of the trait together with the unique infrastructure of Iranian populat...

Fluctuations of Sampling in a Mendelian Population.

In experimental crosses with pedigreed cultures, the observed Mendelian ratios are supposed to be due to the chance combinations of 2” kinds of gametes (n = number of allelomorphic pairs) occurring in equal numbers. The total or aggregate results may show larger or smaller deviations from the calculated ratios, but these deviations frequently lie within reasonable limits of error on the hypothe...
