Genes affected
TMPRSS6 (HGNC:16517): (transmembrane serine protease 6) The protein encoded by this gene is a type II transmembrane serine proteinase that is found attached to the cell surface. The encoded protein may be involved in matrix remodeling processes in the liver. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.30127156).
BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000525 (8/152306) while in subpopulation EAS AF= 0.000772 (4/5184). AF 95% confidence interval is 0.000263. There are 0 homozygotes in gnomad4. There are 5 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.2366G>A (p.R789Q) alteration is located in exon 18 (coding exon 18) of the TMPRSS6 gene. This alteration results from a G to A substitution at nucleotide position 2366, causing the arginine (R) at amino acid position 789 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
