Collection Method: clinical testing

The c.241C>T (p.P81S) alteration is located in exon 1 (coding exon 1) of the SPATA5L1 gene. This alteration results from a C to T substitution at nucleotide position 241, causing the proline (P) at amino acid position 81 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
