The c.41G>A (p.G14D) alteration is located in exon 1 (coding exon 1) of the MVB12A gene. This alteration results from a G to A substitution at nucleotide position 41, causing the glycine (G) at amino acid position 14 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
