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).

The c.1546G>T (p.V516L) alteration is located in exon 9 (coding exon 8) of the MTF1 gene. This alteration results from a G to T substitution at nucleotide position 1546, causing the valine (V) at amino acid position 516 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
