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.
