The c.128G>A (p.C43Y) alteration is located in exon 2 (coding exon 2) of the FAM98C gene. This alteration results from a G to A substitution at nucleotide position 128, causing the cysteine (C) at amino acid position 43 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
