Green List (high evidence)

Comment on list classification: There is sufficient evidence available (three unrelated cases and some experimental evidence) for the promotion of this gene to green rating in the next GMS update.

The ClinGen Motile Ciliopathy expert panel has classified the association of EFCAB1 gene to ciliary dyskinesia, primary, 53 (MONDO:0957991) as 'Strong'. More information can be found in https://search.clinicalgenome.org/CCID:008800.

PMID:36727596 - Three individuals from three unrelated families were identified with three different homozygous variants in EFCAB1 gene (p.Arg98Ter, p.Glu123Ter & p.Glu40Trpfs*16). All three patients presented with situs inversus/ situs ambiguous, while chronic rhino-sinusitis was reported in one, and recurrent pneumonia and respiratory insufficiency were reported in another patient. There is also some functional evidence available.

This gene has also been associated with relevant phenotype in OMIM (MIM #620642).
