This gene and phenotype were reviewed during a meeting on 2nd March 2023 between representatives of the North Thames and Central & South R21 testing GLHs. Clinical review and curation was performed by Lyn Chitty, (North Thames GLH), and Stephanie Allen, Denise Williams, Anna de Burca and Megan Horton-Bell (Central & South GLH). Outcome of review: Confirmed that the phenotype is fetally relevant, support adding to the Fetal anomalies panel as a Green gene.Created: 5 May 2023, 3 p.m. | Last Modified: 5 May 2023, 3 p.m.

Comment on list classification: Confirmed with Stephanie Allen that the GMS Fetal expert group determined there is sufficient evidence to classify this gene as Green (9th May 2023).Created: 10 May 2023, 10:42 a.m. | Last Modified: 10 May 2023, 10:42 a.m.

Comment on list classification: Leaving the rating as amber for now, but with a recommendation of GREEN rating following GMS expert review as to whether the brain anomaly/microcephaly phenotype observed in 5 individuals with missense variants in RAB11A is appropriate for this panel.Created: 14 Aug 2022, 1:19 p.m. | Last Modified: 14 Aug 2022, 1:19 p.m.

PMID: 29100083 - Hamdan et al 2017 - performed WGS on 197 individuals with unexplained Developmental and epileptic encephalopathy and pharmaco-resistant seizures and in their unaffected parents. 2 patients reported with heterozygous missense variants in RAB11A, one of which had seizures (c.244C>T [p.Arg82Cys] variant)
in addition to developing severe ID. 2 other individuals with missense variants in RAB11A and some phenotypic data from the DDD project are described. For 3 of the 4 individuals there are brain MRI data which indicate brain abnormalities including partial agenesis of the corpus callosum, or thin corpus collosum.
PMID: 33875846 - Bertoli-Avella et al 2021 - in a large study of patients with no initial diagnostic variants identified by ES/GS, they identified two different heterozygous missense variants in RAB11A in two unrelated patients (NM_004663.4: c.375G>T, p. Lys125Asn and NM_004663.4: c.380A>G, p. Asp127Gly). Both are reported to have microcephaly (degree not stated) and brain anomalies (both with agenesis of corpus callosum, and one with additional abnormal cortical gyration, myelination abnormalites).Created: 14 Aug 2022, 1:13 p.m. | Last Modified: 14 Aug 2022, 1:14 p.m.
