Collection Method: clinical testing

The c.286C>T (p.P96S) alteration is located in exon 2 (coding exon 2) of the SP9 gene. This alteration results from a C to T substitution at nucleotide position 286, causing the proline (P) at amino acid position 96 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
