Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1615C>T (p.R539W) alteration is located in exon 6 (coding exon 5) of the MZF1 gene. This alteration results from a C to T substitution at nucleotide position 1615, causing the arginine (R) at amino acid position 539 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
