Genes affected

PERP (HGNC:17637): (p53 apoptosis effector related to PMP22) Involved in activation of cysteine-type endopeptidase activity. Predicted to be located in plasma membrane. Predicted to be active in cell-cell junction. Implicated in erythrokeratodermia variabilis and mutilating palmoplantar keratoderma with periorificial keratotic plaques.

The c.238A>G (p.M80V) alteration is located in exon 2 (coding exon 2) of the PERP gene. This alteration results from a A to G substitution at nucleotide position 238, causing the methionine (M) at amino acid position 80 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
