Collection Method: clinical testing

The c.776C>T (p.T259M) alteration is located in exon 4 (coding exon 3) of the ZSCAN16 gene. This alteration results from a C to T substitution at nucleotide position 776, causing the threonine (T) at amino acid position 259 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
