Likely inborn error of metabolism - targeted testing not possible v4.95 NUS1 Achchuthan Shanmugasundram Classified gene: NUS1 as Amber List (moderate evidence)
Likely inborn error of metabolism - targeted testing not possible v4.95 NUS1 Achchuthan Shanmugasundram Added comment: Comment on list classification: As there is sufficient evidence available for the association of monoallelic NUS1 variants with intellectual disability and epilepsy, this gene can be promoted to green rating in the next GMS review.
Likely inborn error of metabolism - targeted testing not possible v4.95 NUS1 Achchuthan Shanmugasundram Gene: nus1 has been classified as Amber List (Moderate Evidence).
Likely inborn error of metabolism - targeted testing not possible v4.94 NUS1 Achchuthan Shanmugasundram Added comment: Comment on mode of inheritance: As reviewed by Dmitrijs Rots, there are more than three unrelated cases and functional evidence available in support of the association of monoallelic NUS1 variants with intellectual disability and epilepsy. This autosomal dominant disorder has been recorded in both OMIM (MIM #617831) and Gene2Phenotype (with 'strong' rating in the DD panel).

However, there is only one family and supporting functional evidence available for the association of biallelic variants with congenital disorder of glycosylation. This phenotype has already been recorded in OMIM (MIM #617082), but not in Gene2Phenotype.

Hence, the MOI should be updated from 'BIALLELIC, autosomal or pseudoautosomal' to 'MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted'.

Likely inborn error of metabolism - targeted testing not possible v2.41 NUS1 Eleanor Williams edited their review of gene: NUS1: Added comment: Provisionally associated with ?Congenital disorder of glycosylation, type 1aa #617082 (AR) in OMIM based on family reported in Park et al 2014 (PMID: 25066056). They describe a family of Roma origin in which 2 out of 4 siblings presented with congenital scoliosis, severe neurological impairment, refractory epilepsy, hearing deficit and visual impairment with discrete bilateral macular lesions. A homozgyous missense mutation, R290H, was found in NUS1 (called NGBR in the paper) by exome sequencing. It segregated with the disease in the family. Patient fibroblasts showed reduced dolichol profiles and enhanced accumulation of free cholesterol as do fibroblasts from mice lacking NgBR.; Changed publications: 25066056; Changed phenotypes: ?Congenital disorder of glycosylation, type 1aa OMIM:617082, congenital disorder of glycosylation, type IAA MONDO:0014904
