Genes affected

PARVA (HGNC:14652): (parvin alpha) This gene encodes a member of the parvin family of actin-binding proteins. Parvins are associated with focal contacts and contain calponin homology domains that bind to actin filaments. The encoded protein is part of the integrin-linked kinase signaling complex and plays a role in cell adhesion, motility and survival. [provided by RefSeq, Dec 2010]

PARVA (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.938

The c.467T>C (p.V156A) alteration is located in exon 4 (coding exon 4) of the PARVA gene. This alteration results from a T to C substitution at nucleotide position 467, causing the valine (V) at amino acid position 156 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
