Abbreviation: CI, confidence interval.
The frequency obtained using the normal chromosomes from patients and their parents. δ, the degree of linkage disequilibrium by Bengtsson and Thomson,24 δ=(PD−PN)/(1−PN), where PD is the frequency of associated allele on del(GJB2-D13S175) carrying chromosomes and PN is the frequency of the same allele on chromosomes without del(GJB2-D13S175). g, the generation number by Risch et al.,22 obtained by use of θ values between D13S175 and D13S1275 or D13S232 from Marshfield map, gMarsh, and from Genethon map, gGen.
P-value for Yates corrected χ2.
At the top, the position of del(GJB2-D13S175) and four microsatellite markers studied. In the middle, haplotypes of del(GJB2-D13S175) carrying chromosomes. For patients A, B, C, F and the healthy Ingush, we were unable to phase mutation-carrying chromosomes into haplotypes by using other family members, therefore, two alleles are separated by slash. Below, the age of del(GJB2-D13S175) in the Ingushes is estimated. Within brackets, the calculations taking into account chromosomes of patients A, B, C, F and the healthy Ingush are present.
