The c.340G>A (p.V114M) alteration is located in exon 5 (coding exon 5) of the JTB gene. This alteration results from a G to A substitution at nucleotide position 340, causing the valine (V) at amino acid position 114 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
