The c.2468T>A (p.I823N) alteration is located in exon 13 (coding exon 11) of the RIMBP2 gene. This alteration results from a T to A substitution at nucleotide position 2468, causing the isoleucine (I) at amino acid position 823 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
