OMIA 000985-9940 : Teat / nipple number in Ovis aries |
A more recent review of Bell's considerable contributions to science is provided by Stansfield (2005). Among many other things, Bell was very interested in the inheritance of deafness (both his mother and his wife were deaf), which led him to write two papers concerning deaf white cats (see OMIA 000259-9685). As it turns out, in these papers deaf white cats are mentioned only in passing; in both reports, Bell is primarily concerned with deafness and skin colour in humans.
Mapping: Peng et al. 2015) "conducted the first GWAS of the supernumerary nipple phenotype in Wadi sheep, a native Chinese sheep breed, based on Ovine Infinium HD SNP BeadChip genotypes in a total of 144 ewes (75 cases with four teats, including two normal and two supernumerary teats, and 69 control cases with two teats). We detected 63 significant SNPs at the chromosome-wise threshold. Additionally, one candidate region (chr1: 170.723-170.734 Mb) was identified by haplotype-based association tests, with one SNP (rs413490006) surrounding functional genes BBX and CD47 on chromosome 1 being commonly identified as significant by the two mentioned analyses."
Zhao et al. (2022): " ... a genome-wide association study was used to identify genetic markers and genes related to the number of teats in the Hu sheep population, a native Chinese sheep breed. ... We also performed quantitative real-time PCR testing of ... identified [positional] candidate genes, identifying three genes with significantly different expression. Our study suggested that the LHFP, DPYSL2, and TDP-43 genes may be related to the number of teats in sheep."
