The c.2845C>T (p.R949C) alteration is located in exon 16 (coding exon 14) of the RIMBP2 gene. This alteration results from a C to T substitution at nucleotide position 2845, causing the arginine (R) at amino acid position 949 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
