Collection Method: clinical testing

The c.760C>T (p.R254C) alteration is located in exon 8 (coding exon 8) of the SPATA17 gene. This alteration results from a C to T substitution at nucleotide position 760, causing the arginine (R) at amino acid position 254 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
