The c.311A>G (p.Y104C) alteration is located in exon 4 (coding exon 2) of the FAM103A1 gene. This alteration results from a A to G substitution at nucleotide position 311, causing the tyrosine (Y) at amino acid position 104 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
