Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.833C>T (p.T278M) alteration is located in exon 7 (coding exon 7) of the SLC39A9 gene. This alteration results from a C to T substitution at nucleotide position 833, causing the threonine (T) at amino acid position 278 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
