The c.1050G>A (p.M350I) alteration is located in exon 2 (coding exon 1) of the ZNF646 gene. This alteration results from a G to A substitution at nucleotide position 1050, causing the methionine (M) at amino acid position 350 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
