Severe microcephaly
Gene: RAD51C
As discussed with the GMS Neurology Specialist Test Group webex call 11th July 2019: The Specialist Test Group all agreed that there is only enough evidence to rate this gene AmberCreated: 29 Jul 2019, 4:18 p.m. | Last Modified: 29 Jul 2019, 4:18 p.m.
Panel Version: 1.62
Added 'watchlist' tag after demoting RAD51C from Green to Amber on the basis of a single case report.Created: 31 Jul 2017, 7:51 a.m.
Comment on list classification: Changed rating from Green to Amber based on re-evaluation of supporting evidence for Fanconi anaemia. Only 1 reported (biallelic) case supporting the FA phenotype (PMID:20400963). Helen Lindsay (Leeds Genetic Laboratory) also confirmed that there is only 1 reported case in literature and they have not identified any pathogenic mutations in FA patients to date. Agreed with Arianna Tucci and Helen Brittain that RAD51C should therefore be Amber on the basis of this single case report.Created: 31 Jul 2017, 7:51 a.m.
Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Source NHS GMS was added to RAD51C.
This gene has been classified as Amber List (Moderate Evidence).
2nd March 2017: Panel review was assessed and panel was revised according to expert review and additional curation. This panel began with an expert gene list from Professor Andrew Jackson (University of Edinburgh) for primary microcephaly (MCPH) and microcephalic primordial dwarfism (MPD). Other disorders are included where microcephaly is a primary feature. Disorders where microcephaly is not the primary presenting feature are not included (e.g. congenital disorders of glycosylation, Proud syndrome, Norrie disease). The panel does not include disorders with a cortical malformation (e.g. lissencephaly) since the Malformations of cortical development' panel would be applied to these patients.
