Genes affected

MT1M (HGNC:14296): (metallothionein 1M) This gene encodes a member of the metallothionein superfamily, type 1 family. Metallothioneins have a high content of cysteine residues that bind various heavy metals. These genes are transcriptionally regulated by both heavy metals and glucocorticoids.

The c.158C>T (p.T53M) alteration is located in exon 3 (coding exon 3) of the MT1M gene. This alteration results from a C to T substitution at nucleotide position 158, causing the threonine (T) at amino acid position 53 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
