Arina Puzriakova Phenotypes for gene: TRAPPC6B were changed from Neurodevelopmental disorder with microcephaly, epilepsy, and brain atrophy, 617862 to Neurodevelopmental disorder with microcephaly, epilepsy, and brain atrophy, OMIM:617862
Rebecca Foulger commented on gene: TRAPPC6B: The Amber review by Konstantinos Varvagiannis (25 Aug 2019) agrees with the current Amber rating of TRAPPC6B: therefore no further curation required.
Rebecca Foulger commented on gene: TRAPPC6B: As discussed with members of the GMS Neurology Specialist Test Group on the Webex call Thursday 8th August 2019 for Clinical Indication R59 Early onset or syndromic epilepsy: Agreed that this gene can remain as Amber.
Rebecca Foulger edited their review of gene: TRAPPC6B: 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: Alison Callaway and John Taylor. Suggested gene rating: Green. ; Changed rating: AMBER
Rebecca Foulger changed review comment from: In 2 patients from a consanguineous family, PMID:28397838 (Harripaul et al. 2018) identified a homozygous truncating variant in TRAPPC6N. The patients were selected for non-syndromic ID, which often presents with epilepsy but seizures were not discussed in the patients.; to: In 2 patients from a consanguineous family, PMID:28397838 (Harripaul et al. 2018) identified a homozygous truncating variant in TRAPPC6N.

Rebecca Foulger Added comment: Comment on list classification: Kept rating as Amber: A founder TRAPPC6B variant was reported in recent PMID:28626029 in Egyptian patients with seizures. Plus additional variant in ID patient from PMID:28397838. Further unrelated cases are required for a diagnostic rating.
