Feb 28, 2024

The c.2057T>C (p.L686S) alteration is located in exon 11 (coding exon 9) of the RIMBP2 gene. This alteration results from a T to C substitution at nucleotide position 2057, causing the leucine (L) at amino acid position 686 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
