Collection Method: clinical testing

The c.640C>T (p.P214S) alteration is located in exon 5 (coding exon 4) of the ZNF684 gene. This alteration results from a C to T substitution at nucleotide position 640, causing the proline (P) at amino acid position 214 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
