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.791T>C (p.I264T) alteration is located in exon 2 (coding exon 1) of the ENPP5 gene. This alteration results from a T to C substitution at nucleotide position 791, causing the isoleucine (I) at amino acid position 264 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
