The c.2806G>A (p.A936T) 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 2806, causing the alanine (A) at amino acid position 936 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
