Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.230T>C (p.M77T) alteration is located in exon 5 (coding exon 3) of the ZMAT5 gene. This alteration results from a T to C substitution at nucleotide position 230, causing the methionine (M) at amino acid position 77 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
