Limb disorders v3.6 UBA2 Eleanor Williams Tag Q4_21_rating was removed from gene: UBA2.
Limb disorders v3.6 UBA2 Eleanor Williams commented on gene: UBA2: The rating of this gene has been updated to green following NHS Genomic Medicine Service approval.
Limb disorders v3.5 UBA2 Eleanor Williams Source Expert Review Green was added to UBA2.
Source NHS GMS was added to UBA2.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Limb disorders v2.60 UBA2 Eleanor Williams Classified gene: UBA2 as Amber List (moderate evidence)
Limb disorders v2.60 UBA2 Eleanor Williams Added comment: Comment on list classification: Leaving rating as amber for now, but with a recommendation for green rating following GMS review. There are now 5 cases reported with split hand malformation and plausible disease causing variants in this gene.
Limb disorders v2.60 UBA2 Eleanor Williams Gene: uba2 has been classified as Amber List (Moderate Evidence).

Limb disorders v2.58 UBA2 Eleanor Williams Tag Q4_21_rating tag was added to gene: UBA2.
Limb disorders v2.58 UBA2 Eleanor Williams edited their review of gene: UBA2: Added comment: As reviewer notes, in PMID: 34159400 (Elsner et al 2021) they report 3 unrelated cases where a variant in UBA2 are reported in individuals with split hand malformation.; Changed rating: GREEN; Changed publications to: 31332306, 24243649, 29988626, 31587267, 34159400
Limb disorders v2.49 UBA2 Zornitza Stark reviewed gene: UBA2: Rating: GREEN; Mode of pathogenicity: None; Publications: 34159400; Phenotypes: Split hand malformation; Mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Limb disorders v2.31 UBA2 Eleanor Williams Classified gene: UBA2 as Amber List (moderate evidence)
Limb disorders v2.31 UBA2 Eleanor Williams Added comment: Comment on list classification: Promoting this gene from red to amber as there are 2 cases with variants in this gene and ectrodactyly reported. Also currently on the Skeletal dysplasia panel as amber.
Limb disorders v2.31 UBA2 Eleanor Williams Gene: uba2 has been classified as Amber List (Moderate Evidence).
Limb disorders v2.30 UBA2 Eleanor Williams gene: UBA2 was added
gene: UBA2 was added to Limb disorders. Sources: Literature
Mode of inheritance for gene: UBA2 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: UBA2 were set to 31332306; 24243649; 29988626; 31587267
Phenotypes for gene: UBA2 were set to split hand-foot malformation MONDO:0016576; aplasia cutis congenita (disease) MONDO:0007145; ectrodactyly
Review for gene: UBA2 was set to AMBER
Added comment: Two reports of SNV in UBA2 in patients with split-hand/foot malformation. There are also reports of microdeletions including the UBA2 gene in 2 patients with split-hand/foot malformation/ectrodactyly

PMID: 31332306 - Yamoto et al 2019 - report one Japanese patient (38-II-1) with split-hand/foot malformation and a de novo c.1324dupT p.(Tyr442Leufs17) variant in UBA2 was found by exome sequencing. Not found in gnomAD. The UBA2 gene was considered a candidate gene because deletion of the region containing this gene (19q13.11) was found in a SHFM patient in this study using aCGH (patient 26-II-3) and in two other studies where microdeletions encompassing the UBA2 gene (among many other genes) were found in singular patients with ectrodactyly; PMID: 24243649 Chowdhury et al 2013 and PMID: 29988626 Abe et al 2019.

PMID: 31587267 - mother and son with aplasia cutis congenita. The son also has bilateral ectrodactyly, a horseshoe kidney, low‐lying conus medullaris and tracheo‐oesophageal fistula. WES identified a heterozygous deletion at c.327delT of UBA2, which leads to a frameshift and early top codon, in both the son and his mother.
