Summaries for KRT71 Gene

Entrez Gene Summary for KRT71 Gene

  • Keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into epithelial keratins and hair keratins. This gene encodes a protein that is expressed in the inner root sheath of hair follicles. The type II keratins are clustered in a region of chromosome 12q13.[provided by RefSeq, Jun 2009]

  • Hypotrichosis 13 (HYPT13) [MIM:615896]: A form of hypotrichosis, a condition characterized by the presence of less than the normal amount of hair and abnormal hair follicles and shafts, which are thin and atrophic. The extent of scalp and body hair involvement can be very variable, within as well as between families. HYPT13 is characterized by sparse woolly hair. {ECO:0000269 PubMed:22592156}.
