The c.938A>G (p.H313R) alteration is located in exon 11 (coding exon 10) of the RFX8 gene. This alteration results from a A to G substitution at nucleotide position 938, causing the histidine (H) at amino acid position 313 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
