The c.283A>C (p.N95H) alteration is located in exon 3 (coding exon 3) of the LYPD2 gene. This alteration results from a A to C substitution at nucleotide position 283, causing the asparagine (N) at amino acid position 95 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
