Dilated Cardiomyopathy
Enlargement and weakening of the left ventricle not explained by coronary artery or valve disease; inherited forms involve TTN, LMNA, RBM20, FLNC, BAG3, DSP, MYH7, TNNT2, DES, PLN and many other genes, and include Barth syndrome and the Emery-Dreifuss muscular dystrophies.
- ClinGen rates the link strong
- 2 GenCC submitters rate it definitive or strong
What knowing changes
Knowing a genetic cause supports earlier heart monitoring and family screening, and for genes with a high arrhythmia risk such as LMNA, FLNC and RBM20 it informs decisions about rhythm monitoring and implantable defibrillators.
How NEXN is laid out
- Coding sequence
- Untranslated region
- Intron
- Direction of transcription
- Known disease-causing sites
- Stretches short reads find hard
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 3.3 kb of the gene's 55.3 kb; 2,028 of those bases code for the protein.
How a genome test reads NEXN
39
positions in NEXN where ClinVar classes a change as pathogenic or likely pathogenic
None of them falls in a region short reads find hard.
A whole genome covers all 55.3 kb of NEXN, introns included, not only the 3.3 kb of exons.
