Collection Method:clinical testing

The c.3047C>T (p.P1016L) alteration is located in exon 16 (coding exon 16) of the PSD3 gene. This alteration results from a C to T substitution at nucleotide position 3047, causing the proline (P) at amino acid position 1016 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
