The c.851G>A (p.R284H) alteration is located in exon 5 (coding exon 4) of the RRAD gene. This alteration results from a G to A substitution at nucleotide position 851, causing the arginine (R) at amino acid position 284 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
