Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal

Variants in this GENE are reported as part of current diagnostic practice

Helen Brittain (Genomics England Curator)

I don't know

Although ID is a feature for a large proportion, it is not a primary feature and seems to be part of the cognitive decline in this progressive condition. May be best suited to other panels

Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal

Phenotypes
Leukoencephalopathy, brain calcifications, and cysts 614561

BRIDGE consortium (NIHRBR-RD)

Green List (high evidence)

This is a pertinent gene from the NIHR BioResource - Rare Diseases Study (NIHRBR-RD) BRIDGE Study : SPEED (Specialist Pathology: Evaluating Exomes in Diagnostics) which covers epilepsies, movement and microcephaly disorders, this gene is on the SPEED_NEURO_20170705 gene list.
