The c.956G>A (p.C319Y) alteration is located in exon 4 (coding exon 4) of the ZNF669 gene. This alteration results from a G to A substitution at nucleotide position 956, causing the cysteine (C) at amino acid position 319 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
