Collection Method: clinical testing

The c.204A>C (p.Q68H) alteration is located in exon 4 (coding exon 3) of the ZNF169 gene. This alteration results from a A to C substitution at nucleotide position 204, causing the glutamine (Q) at amino acid position 68 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
