Collection Method: clinical testing

The c.2084C>A (p.T695K) alteration is located in exon 6 (coding exon 5) of the MZF1 gene. This alteration results from a C to A substitution at nucleotide position 2084, causing the threonine (T) at amino acid position 695 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
