Dec 20, 2023

The c.838G>T (p.V280F) alteration is located in exon 3 (coding exon 2) of the ENPP4 gene. This alteration results from a G to T substitution at nucleotide position 838, causing the valine (V) at amino acid position 280 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
