The c.949A>G (p.K317E) alteration is located in exon 9 (coding exon 7) of the RMND5B gene. This alteration results from a A to G substitution at nucleotide position 949, causing the lysine (K) at amino acid position 317 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
