Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.562C>T (p.R188W) alteration is located in exon 5 (coding exon 4) of the TMPRSS7 gene. This alteration results from a C to T substitution at nucleotide position 562, causing the arginine (R) at amino acid position 188 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
