Genes affected

PVALB (HGNC:9704): (parvalbumin) The protein encoded by this gene is a high affinity calcium ion-binding protein that is structurally and functionally similar to calmodulin and troponin C. The encoded protein is thought to be involved in muscle relaxation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2015]

Ambry Genetics

Dec 14, 2023

The c.178G>A (p.E60K) alteration is located in exon 3 (coding exon 2) of the PVALB gene. This alteration results from a G to A substitution at nucleotide position 178, causing the glutamic acid (E) at amino acid position 60 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
