The c.517G>A (p.A173T) alteration is located in exon 3 (coding exon 3) of the C2CD2L gene. This alteration results from a G to A substitution at nucleotide position 517, causing the alanine (A) at amino acid position 173 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
