Genes affected

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]

The c.674G>A (p.G225D) alteration is located in exon 7 (coding exon 7) of the AAGAB gene. This alteration results from a G to A substitution at nucleotide position 674, causing the glycine (G) at amino acid position 225 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
