Genes affected
MTF1 (HGNC:7428): (metal regulatory transcription factor 1) This gene encodes a transcription factor that induces expression of metallothioneins and other genes involved in metal homeostasis in response to heavy metals such as cadmium, zinc, copper, and silver. The protein is a nucleocytoplasmic shuttling protein that accumulates in the nucleus upon heavy metal exposure and binds to promoters containing a metal-responsive element (MRE).

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 06, 2023 | The c.2204T>C (p.I735T) alteration is located in exon 11 (coding exon 10) of the MTF1 gene. This alteration results from a T to C substitution at nucleotide position 2204, causing the isoleucine (I) at amino acid position 735 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
