The c.119G>A (p.R40Q) alteration is located in exon 3 (coding exon 1) of the RMND5B gene. This alteration results from a G to A substitution at nucleotide position 119, causing the arginine (R) at amino acid position 40 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
