The c.1337G>A (p.C446Y) alteration is located in exon 10 (coding exon 4) of the ZNF45 gene. This alteration results from a G to A substitution at nucleotide position 1337, causing the cysteine (C) at amino acid position 446 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
