The c.1514G>A (p.R505H) alteration is located in exon 6 (coding exon 6) of the BEGAIN gene. This alteration results from a G to A substitution at nucleotide position 1514, causing the arginine (R) at amino acid position 505 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
