Sep 17, 2021

The c.644C>T (p.T215I) alteration is located in exon 4 (coding exon 4) of the ENPP6 gene. This alteration results from a C to T substitution at nucleotide position 644, causing the threonine (T) at amino acid position 215 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
