The c.4322G>A (p.G1441D) alteration is located in exon 1 (coding exon 1) of the RIMBP3B gene. This alteration results from a G to A substitution at nucleotide position 4322, causing the glycine (G) at amino acid position 1441 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
