Rare syndromic craniosynostosis or isolated multisuture synostosis v2.65 ACTG1 Eleanor Williams Tag Q3_21_rating was removed from gene: ACTG1.
Rare syndromic craniosynostosis or isolated multisuture synostosis v2.65 ACTG1 Eleanor Williams commented on gene: ACTG1: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Rare syndromic craniosynostosis or isolated multisuture synostosis v2.64 ACTG1 Eleanor Williams Source Expert Review Green was added to ACTG1.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Rare syndromic craniosynostosis or isolated multisuture synostosis v2.31 ACTG2 Eleanor Williams Added comment: Comment on list classification: Keeping this gene grey as it is not the correct gene for the panel (should be ACTG1).
Rare syndromic craniosynostosis or isolated multisuture synostosis v2.30 ACTG1 Eleanor Williams Classified gene: ACTG1 as Amber List (moderate evidence)
Rare syndromic craniosynostosis or isolated multisuture synostosis v2.30 ACTG1 Eleanor Williams Added comment: Comment on list classification: Promoting this gene from red to amber, with the recommendation of green rating following GMS review. More than 3 cases reported with disease-associated variants in this gene, with Trigonocephaly/metopic ridge reported as part of the phenotype.
Rare syndromic craniosynostosis or isolated multisuture synostosis v2.30 ACTG1 Eleanor Williams Gene: actg1 has been classified as Amber List (Moderate Evidence).
Rare syndromic craniosynostosis or isolated multisuture synostosis v2.29 ACTG1 Eleanor Williams Tag Q3_21_rating tag was added to gene: ACTG1.
Rare syndromic craniosynostosis or isolated multisuture synostosis v2.29 ACTG1 Eleanor Williams gene: ACTG1 was added
gene: ACTG1 was added to Craniosynostosis. Sources: Literature
missense tags were added to gene: ACTG1.
Mode of inheritance for gene: ACTG1 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: ACTG1 were set to 22366783; 25052316; 27240540
Phenotypes for gene: ACTG1 were set to Baraitser-Winter syndrome 2, OMIM:614583
Review for gene: ACTG1 was set to GREEN
Added comment: Associated with Baraitser-Winter syndrome 2 OMIM:614583 (AD) in OMIM.

PMID: 22366783 - Rivière et al 2012 - 8 patients with Baraitser-Winter syndrome in which a heterozygous missense mutation was identified in the ACTG1 gene. In 7 patients the mutation was found to have occurred de novo (no parental DNA in 8th patient). Trigonocephaly was noted in 7 of the patients.

PMID: 25052316 - Verloes et al 2015 - report on 1 new case of a patient with a missense variant in ACTG1 (same variant as reported in Riviere et al) and bring together information from the Riviere patients with this one. They state that Trigonocephaly/metopic ridge is reported in 4/8 cases (50%) which contradicts the table in the Riviere paper which puts the number as higher.

PMID: 27240540 - Donato et al 2016 - report on 7 new unrelated patients with 6 mutations in ACTG1. Clinical photographs were available for 6 of these patients, and only 1/6 displayed a metopic ridge.
