The c.310A>C (p.N104H) alteration is located in exon 1 (coding exon 1) of the VN1R2 gene. This alteration results from a A to C substitution at nucleotide position 310, causing the asparagine (N) at amino acid position 104 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
