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).

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MTF1. . Gene score misZ 2.5403 (greater than the threshold 3.09). Trascript score misZ 3.4658 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 40.
BP4
Computational evidence support a benign effect (MetaRNN=0.039250344).
BS2
High AC in GnomAdExome4 at 5 AD gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2022The c.1471G>A (p.A491T) alteration is located in exon 9 (coding exon 8) of the MTF1 gene. This alteration results from a G to A substitution at nucleotide position 1471, causing the alanine (A) at amino acid position 491 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
