Genes affected

IQCH (HGNC:25721): (IQ motif containing H)

IQCH links:

AAGAB (HGNC:25662): (alpha and gamma adaptin binding protein) The protein encoded by this gene interacts with the gamma-adaptin and alpha-adaptin subunits of complexes involved in clathrin-coated vesicle trafficking. Mutations in this gene are associated with type I punctate palmoplantar keratoderma. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2012]
