Genes affected

CAVIN3 (HGNC:9400): (caveolae associated protein 3) The protein encoded by this gene was identified as a binding protein of the protein kinase C, delta (PRKCD). The expression of this gene in cultured cell lines is strongly induced by serum starvation. The expression of this protein was found to be down-regulated in various cancer cell lines, suggesting the possible tumor suppressor function of this protein. [provided by RefSeq, Jul 2008]

ENSG00000282556 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.06875762).
• BS2: High AC in GnomAdExome4 at 26 AD gene.

Collection Method: clinical testing

The c.470A>C (p.Q157P) alteration is located in exon 2 (coding exon 2) of the PRKCDBP gene. This alteration results from a A to C substitution at nucleotide position 470, causing the glutamine (Q) at amino acid position 157 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
