Genes affected

SELENBP1 (HGNC:10719): (selenium binding protein 1) This gene encodes a member of the selenium-binding protein family. Selenium is an essential nutrient that exhibits potent anticarcinogenic properties, and deficiency of selenium may cause certain neurologic diseases. The effects of selenium in preventing cancer and neurologic diseases may be mediated by selenium-binding proteins, and decreased expression of this gene may be associated with several types of cancer. The encoded protein may play a selenium-dependent role in ubiquitination/deubiquitination-mediated protein degradation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Apr 2012]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151365568-C-A is Pathogenic according to our data. Variant chr1-151365568-C-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 549495.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr1-151365568-C-A is described in Lovd as [Pathogenic].

This variant is interpreted as a Likely Pathogenic, for Extraoral halitosis, Autosomal Recessive inheritance. The following ACMG Tag(s) were applied: PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PS3 => Well-established functional studies show a deleterious effect (PMID:29255262). PP1 => Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease. -
