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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000274 (40/1461724) while in subpopulation SAS AF= 0.000464 (40/86252). AF 95% confidence interval is 0.00035. There are 0 homozygotes in gnomad4_exome. There are 32 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.392T>C (p.V131A) alteration is located in exon 3 (coding exon 3) of the PERP gene. This alteration results from a T to C substitution at nucleotide position 392, causing the valine (V) at amino acid position 131 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
