The c.1264A>G (p.M422V) alteration is located in exon 2 (coding exon 1) of the ZBTB45 gene. This alteration results from a A to G substitution at nucleotide position 1264, causing the methionine (M) at amino acid position 422 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
