The c.748A>T (p.N250Y) alteration is located in exon 2 (coding exon 1) of the ENPP4 gene. This alteration results from a A to T substitution at nucleotide position 748, causing the asparagine (N) at amino acid position 250 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
