The c.935A>G (p.K312R) alteration is located in exon 6 (coding exon 6) of the ENPP6 gene. This alteration results from a A to G substitution at nucleotide position 935, causing the lysine (K) at amino acid position 312 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
