Collection Method: clinical testing

The c.116C>T (p.S39F) alteration is located in exon 1 (coding exon 1) of the PPWD1 gene. This alteration results from a C to T substitution at nucleotide position 116, causing the serine (S) at amino acid position 39 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
