The c.812A>G (p.K271R) alteration is located in exon 4 (coding exon 4) of the ZNF805 gene. This alteration results from a A to G substitution at nucleotide position 812, causing the lysine (K) at amino acid position 271 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
