Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.537T>G (p.C179W) alteration is located in exon 8 (coding exon 7) of the MROH9 gene. This alteration results from a T to G substitution at nucleotide position 537, causing the cysteine (C) at amino acid position 179 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
