Genes affected

ENPP5 (HGNC:13717): (ectonucleotide pyrophosphatase/phosphodiesterase family member 5) This gene encodes a type-I transmembrane glycoprotein. Studies in rat suggest the encoded protein may play a role in neuronal cell communications. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2014]

The c.1336G>T (p.V446L) alteration is located in exon 4 (coding exon 3) of the ENPP5 gene. This alteration results from a G to T substitution at nucleotide position 1336, causing the valine (V) at amino acid position 446 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
