Severe microcephaly v2.287 NARS Eleanor Williams Tag for-review was removed from gene: NARS.
Severe microcephaly v2.282 NARS Sarah Leigh commented on gene: NARS
Severe microcephaly v2.281 NARS Eleanor Williams Source Expert Review Green was added to NARS.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Severe microcephaly v2.53 NARS Arina Puzriakova commented on gene: NARS: Added new-gene-name tag, new approved HGNC gene symbol for NARS is NARS1
Severe microcephaly v2.53 NARS Arina Puzriakova Classified gene: NARS as Amber List (moderate evidence)
Severe microcephaly v2.53 NARS Arina Puzriakova Added comment: Comment on list classification: There is sufficient evidence to rate this gene Green at the next GMS panel update (added 'for-review' tag)
Severe microcephaly v2.53 NARS Arina Puzriakova Gene: nars has been classified as Amber List (Moderate Evidence).
Severe microcephaly v2.52 NARS Arina Puzriakova gene: NARS was added
gene: NARS was added to Severe microcephaly. Sources: Literature
new-gene-name, for-review tags were added to gene: NARS.
Mode of inheritance for gene: NARS was set to BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Publications for gene: NARS were set to 32738225; 32788587
Phenotypes for gene: NARS were set to Neurodevelopmental disorder with microcephaly, impaired language, and gait abnormalities, autosomal recessive, OMIM:619091; Neurodevelopmental disorder with microcephaly, impaired language, epilepsy, and gait abnormalities, autosomal dominant, OMIM:619092
Review for gene: NARS was set to GREEN
Added comment: Associated with relevant phenotype in OMIM, and in Gene2Phenotype with 'confirmed' disease confidence for 'NARS1 Neurodevelopmental Disorder (monoallelic)' and 'probable' for 'NARS1 Neurodevelopmental Disorder (biallelic)'

Total of 24 patients from 13 unrelated families with biallelic variants in the NARS1 gene (PMIDs: 32738225 and 32788587) and 8 unrelated patients with de novo heterozygous variants (PMIDs: 32738225). Microcephaly was observed in the majority of cases (90%), with severity relevant to this panel (≥ 3 SD). These cases predominantly presented with primary microcephaly; however, secondary microcephaly was also noted. Other features include GDD/ID, seizures, ataxia, and dysmorphism. Supportive functional data.
