5 individuals from 3 consanguineous families reported originally; same homozygous missense in all raising concern about this being a founder variant. Another individual reported with different variant as part of a study reporting large number of novel/emerging genes in consanguineous cohort.

On re-reviewing this gene, the mouse model was not a knockout gene model of GEMIN4. PMID: 30237576 is a new publication that describes another case with the same variant as that reported by PMID: 25558065. The affected individual is from the same region as the previous publication. Therefore, there is insufficient evidence to support a gene-disease status and this gene should be downgraded from Green to Amber at the next review.

GEMIN4 is associated with a phenotype on OMIM but not Gene2Phenotype. It is an amber gene on the ID panel (code 285, version 2.1017). PMID: 25558065 reported on 5 affected patients from 3 unrelated consanguineous Saudi families with neurodevelopmental disorder, microcephaly cataracts and renal abnormalities. PMID: 27878435 reported on a different family with a different variant that was previously reported. The same paper also performed mouse studies and found that the gene is down regulated in key gene knockout mice with lens defects. Therefore, there is enough evidence for this gene to be green.
