Intellectual disability - microarray and sequencing v3.1676 RAB11A Eleanor Williams Classified gene: RAB11A as Amber List (moderate evidence)
Intellectual disability - microarray and sequencing v3.1676 RAB11A Eleanor Williams Added comment: Comment on list classification: Leaving the rating as amber just now, but with a recommendation of GREEN rating following GMS review. There are now 6 unrelated individuals with an intellectual disability phenotype reported and missense variants in this gene. Although there is little clinical data available the number of cases adds weight to this gene-disease association.

Added comment: PMID: 29100083 (by Hamdan et al.) is a study on de novo mutations in individuals with developmental and epileptic encephalopathies (DEE).

One subject from this study was found to harbor a de novo missense RAB11A variant [NM_004663.4:c.244C>T or p.(Arg82Cys)]. This individual presented with epilepsy, developmental regression and severe ID.

In their cohort the authors also identified an additional individual with a de novo missense variant [(c.71A>G or p.(Lys24Arg)] who had moderate ID and abnormal EEG albeit without seizures.

De novo variants in RAB11A had previously been identified in 3 DDD study participants with ID.

The authors obtained clinical details on the 2 individuals with the p.(Ser154Leu) variant [NM_004663.4:c.461C>T]. One of them had moderate ID without seizures while the other had moderate global DD at the age of 4 years, also without seizures.

A third DDD study participant harbored another missense variant p.(Lys13Asn) [NM_004663.4:c.39A>C] as a de novo occurence. The authors did not manage to obtain clinical details although this patient was reported to have abnormalities of the nervous system in Decipher.

The features of all 4 individuals for whom clinical details were available are summarized in table 7.

Previous studies suggest that RAB11A has a role in NTRK2 and AMPA receptor recycling at the post-synaptic membrane of neurons and - as a result - in regulation of synaptic plasticity.
-----------
RAB11A is not associated with any phenotype in OMIM.

This gene is included in the DD panel of G2P, associated with epilepsy and intellectual disability (disease confidence: probable).

It is also included in gene panels for ID offered by some diagnostic laboratories.
-----------
As a result, it can be considered for inclusion in this panel as amber or possibly green (3 unrelated individuals with ID, 1 further with DD at a young age).
