The c.2977G>A (p.D993N) alteration is located in exon 17 (coding exon 15) of the RIMBP2 gene. This alteration results from a G to A substitution at nucleotide position 2977, causing the aspartic acid (D) at amino acid position 993 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
