To date, EXOC3L2 variants have not been associated with a phenotype in OMIM or Gen2Phen. However, four homozygous EXOC3L2 variants have been reported in four unrelated cases with a novel syndrome that affects hindbrain development, kidney and possibly the bone marrow (PMID: 28749478, 27894351; 30327448; 34974531).

Andrea Nemeth (University of Oxford)

Red List (low evidence)

Only one consanguineous family with above phenotype in 3 children.

Homozygous loss of function mutation.

No functional data to support this genes role in cilial function.

Mutations in this gene seems to be an extremely rare cause of the above phenotype, therefore warranting inclusion in rare unexplained fetal loss/congenital malformations but no current data to support being included within Rare Cilial phenotypes.
