Bartter Disease
- Bartter Syndrome Type 4Autosomal recessive
A form of Bartter syndrome characterized by maternal polyhydramnios, premature delivery, salt loss, polyuria and sensorineural deafness, associated with hypokalemic and hypochloremic metabolic alkalosis, increased levels of plasma renin and aldosterone, and low to normal blood pressure. Urinary calcium excretion rates are variable, and nephrocalcinosis is typically absent.
- ClinGen rates the link definitive
- 5 GenCC submitters rate it definitive or strong
- Bartter Syndrome
A group of inherited salt-wasting kidney tubule disorders, caused by genes such as SLC12A1, KCNJ1, CLCNKB, BSND and CASR, with low potassium, metabolic alkalosis and high urine calcium.
- ClinGen rates the link definitive
- 5 GenCC submitters rate it definitive or strong
What knowing changes
Knowing guides salt and potassium replacement and monitoring of growth and kidney calcification.
Inheritance
- Autosomal recessive
- It takes a changed copy from each parent. With one, you are a carrier and usually unaffected; when both parents are carriers, each child has a one-in-four chance of inheriting two.
How BSND is laid out
- Coding sequence
- Untranslated region
- Intron
- Direction of transcription
- Known disease-causing sites
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 9.8 kb of the gene's 18.2 kb; 963 of those bases code for the protein.
How a genome test reads BSND
27
positions in BSND 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 18.2 kb of BSND, introns included, not only the 9.8 kb of exons.
