The c.2919G>A (p.M973I) alteration is located in exon 3 (coding exon 1) of the RBM12B gene. This alteration results from a G to A substitution at nucleotide position 2919, causing the methionine (M) at amino acid position 973 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
