Mendeliome v1.2099 UBTF Zornitza Stark edited their review of gene: UBTF: Added comment: PMID 39366741: 3 Chinese patients with global developmental delay, intellectual disability, social challenges and dysmorphism (wide forehead, sparse eyebrows, hypertelorism, narrow palpebral fissures, single-fold eyelids, flat nasal bridge, anteverted nares, a long philtrum and a thin upper lip), but no neuroregression (but aged 1.8yrs-4.8yrs). WES with SNV/CNV analysis showed:
-nonsense variant c.1327C>T p. (Arg443Ter) - parental segregation not possible
-de novo ~46 kb deletion at 17q21.31 containing 7 genes but UBTF as only OMIM Morbid gene
-de novo ~106kb deletion at 17q21.31 containing 10 genes but UBTF as only relevant OMIM Morbid gene (other one was SLC4A1)

Propose haploinsufficiency presents with different phenotype to CONDBA which is due to GOF variant.

AMBER for this mechanism and phenotype.; Changed publications: 28777933, 29300972, 39366741; Changed phenotypes: Neurodegeneration, childhood-onset, with brain atrophy, MIM# 617672, MONDO:0044701, Neurodevelopmental disorder, MONDO:0700092, UBTF-related

Added comment: Total 4 individuals from 3 families (2 known to be from same ethnic origin: Oriental-Jewish) with adult onset retinitis pigmentosa. All individuals had same homozygous frameshift variant in SLC4A7 gene (p.P670Sfs*6). RNA seq analysis revealed retinal expression in human and mouse samples. Immunohistochemistry of human and mouse retina revealed relatively strong expression in various retinal layers. Western blot analysis in fibroblasts from 1 patient showed absence of encoded protein.

Added comment: PMID: 37459438 Fasham et al 2023 (Brain) report 10 affected individuals from 5 unrelated families with biallelic LoF variants in this gene with a novel neurodevelopmental disorder.

Phenotypic features include hypotonia in infancy, delayed psychomotor development, typically severe ID, progressive postnatal microcephaly, ASD traits, corpus callosal abnormalities and 'slit-like' lateral ventricles. These phenotypic features were recapitulated in knockout mice with additional supportive functional studies.

Isolated seizures was reported in 2/10 cases.

Review for gene: SLC4A3 was set to AMBER
Added comment: Moderate evidence for autosomal dominant short QT syndrome 1 by ClinGen /gene curation expert panel (PMID: 34557911). A single missense variant (absent gnomAD) identified in two SQTS families. In family 1, it segregated with SQTS (QTc<370ms) in 23 carriers, and 19 non-carriers had a QTc>370ms. In family 2, it segregated in 4 individuals. Experimental evidence from in vitro and zebrafish models suggests reduced membrane localization of the mutated protein leads to intracellular alkalinization and shortening of the cardiomyocyte action potential duration.
ClinGen expert panel was divided between strong (4 votes) and moderate (5 votes).
