The c.349C>T (p.P117S) alteration is located in exon 2 (coding exon 2) of the SPATA3 gene. This alteration results from a C to T substitution at nucleotide position 349, causing the proline (P) at amino acid position 117 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
