The c.947A>G (p.H316R) alteration is located in exon 7 (coding exon 7) of the KIAA1328 gene. This alteration results from a A to G substitution at nucleotide position 947, causing the histidine (H) at amino acid position 316 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
