The c.386A>G (p.Y129C) alteration is located in exon 3 (coding exon 3) of the FAM173A gene. This alteration results from a A to G substitution at nucleotide position 386, causing the tyrosine (Y) at amino acid position 129 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
