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 eas. gnomad4_exome allele frequency = 0.0000205 (30/1461668) while in subpopulation EAS AF= 0.000731 (29/39698). AF 95% confidence interval is 0.000522. There are 0 homozygotes in gnomad4_exome. There are 12 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.388C>T (p.P130S) alteration is located in exon 3 (coding exon 3) of the PERP gene. This alteration results from a C to T substitution at nucleotide position 388, causing the proline (P) at amino acid position 130 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
