The c.442G>A (p.V148M) alteration is located in exon 3 (coding exon 3) of the RIC8A gene. This alteration results from a G to A substitution at nucleotide position 442, causing the valine (V) at amino acid position 148 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
