Genes affected

POPDC3 (HGNC:17649): (popeye domain containing 3) This gene encodes a member of the POP family of proteins containing three putative transmembrane domains. This gene is expressed in cardiac and skeletal muscle and may play an important role in these tissues during development. Alternatively spliced transcript variants have been found.

The c.595G>C (p.V199L) alteration is located in exon 4 (coding exon 3) of the POPDC3 gene. This alteration results from a G to C substitution at nucleotide position 595, causing the valine (V) at amino acid position 199 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
