The c.791A>G (p.H264R) alteration is located in exon 6 (coding exon 6) of the KHDRBS2 gene. This alteration results from a A to G substitution at nucleotide position 791, causing the histidine (H) at amino acid position 264 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
