Genes affected

PAQR4 (HGNC:26386): (progestin and adipoQ receptor family member 4) Predicted to enable signaling receptor activity. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

PKMYT1 (HGNC:29650): (protein kinase, membrane associated tyrosine/threonine 1) This gene encodes a member of the serine/threonine protein kinase family. The encoded protein is a membrane-associated kinase that negatively regulates the G2/M transition of the cell cycle by phosphorylating and inactivating cyclin-dependent kinase 1. The activity of the encoded protein is regulated by polo-like kinase 1. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.948

The c.370T>C (p.C124R) alteration is located in exon 2 (coding exon 2) of the PAQR4 gene. This alteration results from a T to C substitution at nucleotide position 370, causing the cysteine (C) at amino acid position 124 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
