Genes affected
KRTAP10-8 (HGNC:20525): (keratin associated protein 10-8) Enables identical protein binding activity. Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]
TSPEAR (HGNC:1268): (thrombospondin type laminin G domain and EAR repeats) This gene encodes a protein that contains a N-terminal thrombospondin-type laminin G domain and several tandem arranged epilepsy-associated repeats (EARs). A mutation in this gene is the cause of autosomal recessive deafness-98. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]
TSPEAR Gene-Disease associations (from GenCC):
  • ectodermal dysplasia 14, hair/tooth type with or without hypohidrosis
