Collection Method: clinical testing

The c.536C>G (p.T179S) alteration is located in exon 6 (coding exon 4) of the ZNF226 gene. This alteration results from a C to G substitution at nucleotide position 536, causing the threonine (T) at amino acid position 179 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
