KRT71 and Woolly hair: Through gene function annotation, we identified seven candidate genes associated with ACC on SSC5, namely KRT71, KRT1, KRT4, ITGB7, CSAD, RARG, and SP7. The KRT71 gene encodes a protein expressed in the inner root sheath of hair follicles and is implicated in disorders such as Hypotrichosis 13 and Familial Woolly Hair Syndrome (https://www.ncbi.nlm.nih.gov/gene/112802#summary).
