The c.1493G>A (p.C498Y) alteration is located in exon 6 (coding exon 4) of the ZNF343 gene. This alteration results from a G to A substitution at nucleotide position 1493, causing the cysteine (C) at amino acid position 498 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
