Congenital Myopathies
- Nemaline myopathy
A congenital myopathy defined by rod-shaped structures in muscle fibers, most often caused by NEB or ACTA1 variants.
- ClinGen rates the link definitive
- 6 GenCC submitters rate it definitive or strong
How NEB is laid out
- Coding sequence
- Untranslated region
- Intron
- Direction of transcription
- Known disease-causing sites
- Stretches short reads find hard
- Variants with a page
Exons of the gene's MANE Select transcript (release v1.5), from NCBI and EMBL-EBI, on the GRCh38 reference genome.
Chromosome bands from UCSC's GRCh38 ideogram (2022-10-29).
Nearby genes from Ensembl release 116, on GRCh38.
Exons make up 26.2 kb of the gene's 249.1 kb; 25,578 of those bases code for the protein.
How a genome test reads NEB
1,802
positions in NEB where ClinVar classes a change as pathogenic or likely pathogenic
187 of them (10%) fall in regions short reads find hard.
- Low mappability (187 sites)Regions where 100 bp or 250 bp reads cannot be placed uniquely.
- Segmental duplications (154 sites)Copies of at least 1 kb sharing at least 90% identity with another part of the genome (paralogues, pseudogenes); reads may align to the wrong copy.
A whole genome covers all 249.1 kb of NEB, introns included, not only the 26.2 kb of exons.
