Collection Method:clinical testing

The c.704C>T (p.S235F) alteration is located in exon 4 (coding exon 4) of the THAP8 gene. This alteration results from a C to T substitution at nucleotide position 704, causing the serine (S) at amino acid position 235 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
