OMIA 002022-9913 : Arthrogryposis multiplex congenita, CHRNB1-related in Bos taurus

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 616314 , 616313

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2016

Inheritance: Agerholm et al. (2016) provided pedigree evidence consistent with autosomal recessive inheritance.

Mapping: Agerholm et al. (2016): "a single genomic region of extended homozygosity of 21.5 Mb on chromosome 19"

Molecular basis: Agerholm et al. (2016): "a single base deletion in the first exon of CHRNB1 (c.55delG) introducing a premature stop codon (p.Ala19Profs47*) in the second exon, truncating 96 % of the protein."

Breed: Red Danish.

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
