Intellectual disability v6.12 MAST4 Eleanor Williams Tag gene-checked tag was added to gene: MAST4.
Intellectual disability v6.11 MAST4 Achchuthan Shanmugasundram Tag Q4_23_promote_green was removed from gene: MAST4.
Intellectual disability v6.11 MAST4 Sarah Leigh edited their review of gene: MAST4: Added comment: The rating of this gene has been updated to Green and the mode of inheritance set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted following NHS Genomic Medicine Service approval.; Changed mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Intellectual disability v6.10 MAST4 Achchuthan Shanmugasundram Source Expert Review Green was added to MAST4.
Source NHS GMS was added to MAST4.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Intellectual disability v5.328 MAST4 Sarah Leigh Tag Q4_23_promote_green tag was added to gene: MAST4.
Intellectual disability v5.328 MAST4 Sarah Leigh edited their review of gene: MAST4: Added comment: MAST4 variants have not been associated with a phenotype in OMIM, Gen2Phen or MONDO to date. PMID: 36910266 reports three de novo heterozygous MAST4 missense variants in four unrelated cases, with a neurodevelopmental disorder, including cognitive delay/intellectual disability and PMID: 33057194 reports four heterozygous MAST4 missense variants in four unrelated cases and a terminating variant in an additional case, from a cohort of 31,058 parent-offspring trios of individuals with developmental disorders. Between these two publications there are five missense MAST4 variants and one terminating variant. Variant c.4412C>T (p.Thr1471Ile) was seen in three unrelated cases.; Changed rating: GREEN
Intellectual disability v5.328 MAST4 Sarah Leigh Classified gene: MAST4 as Amber List (moderate evidence)
Intellectual disability v5.328 MAST4 Sarah Leigh Added comment: Comment on list classification: There is enough evidence for this gene to be rated GREEN at the next major review.
Intellectual disability v5.328 MAST4 Sarah Leigh Gene: mast4 has been classified as Amber List (Moderate Evidence).
Intellectual disability v5.327 MAST4 Sarah Leigh Classified gene: MAST4 as Amber List (moderate evidence)
Intellectual disability v5.327 MAST4 Sarah Leigh Gene: mast4 has been classified as Amber List (Moderate Evidence).
