Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.523C>T (p.R175C) alteration is located in exon 4 (coding exon 4) of the SPATA4 gene. This alteration results from a C to T substitution at nucleotide position 523, causing the arginine (R) at amino acid position 175 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
