Severe microcephaly
Gene: PALB2
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.

This gene was reviewed as part of the structural neurological disorders working group webex on 11th July. Although microcephaly is recognised as a feature of Fanconi anaemia, the evidence for microcephaly in association with biallelic PALB2 variants was questioned. The consensus was for an amber rating.Created: 19 Jul 2019, 1:44 p.m. | Last Modified: 19 Jul 2019, 1:44 p.m.

Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal
Source NHS GMS was added to PALB2.
Gene: palb2 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.
