The c.1332G>A (p.M444I) alteration is located in exon 2 (coding exon 2) of the MSL2 gene. This alteration results from a G to A substitution at nucleotide position 1332, causing the methionine (M) at amino acid position 444 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
