The c.1142A>G (p.H381R) alteration is located in exon 5 (coding exon 5) of the ZNF699 gene. This alteration results from a A to G substitution at nucleotide position 1142, causing the histidine (H) at amino acid position 381 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
