Review for gene: SECISBP2 was set to GREEN
Added comment: Biallelic defects in this gene cause a multi system disorder with deficiency of most human selenoproteins. Phenotypes listed here are associated with a biochemical signature of elevated circulating T4 (thyroxine) and low plasma selenium.

Since some pathogenic variants can be in non-coding regions and cryptic, we suggest a high index of suspicion even in cases of aortic aneurysm with an apparently monoallelic SECISBP2 defect. In such cases, we advocate measuring circulating T4 and selenium; if these biomarker levels are abnormal a cryptic mutation on the other allele should be sought.
