Collection Method: clinical testing

The c.811C>A (p.H271N) alteration is located in exon 3 (coding exon 1) of the ZNF391 gene. This alteration results from a C to A substitution at nucleotide position 811, causing the histidine (H) at amino acid position 271 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
