Arina Puzriakova Phenotypes for gene: TBCD were changed from Encephalopathy, progressive, early-onset, with brain atrophy and thin corpus callosum, 617193; seizures; West syndrome to Encephalopathy, progressive, early-onset, with brain atrophy and thin corpus callosum, OMIM:617193; Early-onset progressive diffuse brain atrophy-microcephaly-muscle weakness-optic atrophy syndrome, MONDO:0044646
Rebecca Foulger edited their review of gene: TBCD: Added comment: Review and rating collated by Tracy Lester (Oxford Medical Genetics Laboratories Oxford University Hospitals NHS Foundation Trust, 2019_02_06) on behalf of Wessex and West Midlands GLH for GMS Neurology specialist test group, for Clinical Indication R59 'Early onset or syndromic epilepsy'. Review contributors: John Taylor and Helen Lord. Suggested gene rating: Green. ; Changed rating: AMBER
Rebecca Foulger Added comment: Comment on list classification: Updated rating from Amber to Green. Green review. Confirmed DD-G2P gene for Early-Onset Neurodegenerative Encephalopathy, which can present with seizures. Sufficient cases of seizures (>3) in PMID:27666370 and PMID:27666374 for inclusion on panel.

Rebecca Foulger commented on gene: TBCD: In 8 children from 4 unrelated families, Miyake et al (PMID:27666374) identified homozygous or compound het variants in TBCD. Seizures were reported in 3 families (Table 2) and were reported as GTS (Chinese family 3), GTS/GTCS (Israel family 4) and West syndrome/cataplexy (Japanese Family 2).
