Skeletal dysplasia v4.4 NMNAT1 Achchuthan Shanmugasundram Publications for gene: NMNAT1 were set to 32533184; 33668384
Skeletal dysplasia v4.4 NMNAT1 Achchuthan Shanmugasundram Publications for gene: NMNAT1 were set to 32533184; 33668384
Skeletal dysplasia v4.4 NMNAT1 Achchuthan Shanmugasundram Publications for gene: NMNAT1 were set to 32533184
Skeletal dysplasia v4.3 NMNAT1 Achchuthan Shanmugasundram Classified gene: NMNAT1 as Amber List (moderate evidence)
Skeletal dysplasia v4.3 NMNAT1 Achchuthan Shanmugasundram Added comment: Comment on list classification: As two of the three reported families were distantly related, this gene should only be rated AMBER with the current evidence. However, 'watchlist' tag was added to review the rating in light of new evidence in the future.
Skeletal dysplasia v4.3 NMNAT1 Achchuthan Shanmugasundram Gene: nmnat1 has been classified as Amber List (Moderate Evidence).
Skeletal dysplasia v4.2 NMNAT1 Achchuthan Shanmugasundram commented on gene: NMNAT1: The 'cnv' tag was added as two of the reported cases harboured duplication variants in homozygous state and the third case harboured duplication variant together with a splicing variant.
Skeletal dysplasia v4.2 NMNAT1 Achchuthan Shanmugasundram Tag watchlist tag was added to gene: NMNAT1.
Tag cnv tag was added to gene: NMNAT1.
Skeletal dysplasia v4.2 NMNAT1 Achchuthan Shanmugasundram reviewed gene: NMNAT1: Rating: AMBER; Mode of pathogenicity: None; Publications: 32533184, 33668384; Phenotypes: Spondyloepiphyseal dysplasia, sensorineural hearing loss, intellectual developmental disorder, and Leber congenital amaurosis, OMIM:619260; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Skeletal dysplasia v2.87 NMNAT1 Zornitza Stark gene: NMNAT1 was added
gene: NMNAT1 was added to Skeletal dysplasia. Sources: Literature
Mode of inheritance for gene: NMNAT1 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: NMNAT1 were set to 32533184
Phenotypes for gene: NMNAT1 were set to Spondyloepiphyseal dysplasia, sensorineural hearing loss, intellectual disability, and Leber congenital amaurosis (SHILCA), MIM#619260
Review for gene: NMNAT1 was set to GREEN
gene: NMNAT1 was marked as current diagnostic
Added comment: The association with LCA is well established.

New report of a syndromic LCA disorder and note also unusual variant type. Three families, but two are distantly related (shared haplotype). The affected children in those two families were homozygous for 7.4-kb duplication involving the last 2 exons of the NMNAT1 gene, spanning the beginning of intron 3 to the middle of the 3-prime UTR (chr1:10,036,359-10,043,727, GRCh37). The third affected individual was compound het for the duplication and a splicing variant.
