Genes affected

PAQR8 (HGNC:15708): (progestin and adipoQ receptor family member 8) Predicted to enable steroid binding activity and steroid hormone receptor activity. Predicted to be involved in response to steroid hormone. Located in Golgi apparatus and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

EFHC1 (HGNC:16406): (EF-hand domain containing 1) This gene encodes an EF-hand-containing calcium binding protein. The encoded protein likely plays a role in calcium homeostasis. Mutations in this gene have been associated with susceptibility to juvenile myoclonic epilepsy and juvenile absence epilepsy. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.34328175).

The c.382C>G (p.L128V) alteration is located in exon 2 (coding exon 1) of the PAQR8 gene. This alteration results from a C to G substitution at nucleotide position 382, causing the leucine (L) at amino acid position 128 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
