OMIA:002031-9615 : Lundehund syndrome in Canis lupus familiaris (dog)

Categories: Digestive / alimentary phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 610341 (gene)

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2016

Species-specific symbol: LS

Inheritance: Metzger et al. (2016): " A complex segregation analysis revealed a recessive major gene model as the most likely mode of inheritance with the lowest −2 log-likelihood at 52.6".

Mapping: Metzger et al. (2016): "Comprehensive analysis of bead chip and whole-genome sequencing data for LS in the Lundehund resulted in a genome-wide association signal on CFA 34 and LS-specific runs of homozygosity (ROH) in this region."

Molecular basis: Metzger et al. (2016): "Filtering analysis for variants with predicted high or moderate effects revealed a missense mutation in LEPREL1 [also known as P3H2] 1.2 Mb proximal to the region of the genome-wide association, which was shown to be significantly associated with LS."

Clinical features: Metzger et al. (2016): "the Lundehund harbors a breed disposition for a syndrome comprising particular features of protein-losing enteropathy (PLE), intestinal lymphangiectasia, gastrointestinal disturbance, inflammatory bowel disease and malabsorption designated as Lundehund syndrome (LS) . . . . Clinical signs are diarrhea, vomiting, weight loss, edema and apathy often accompanied with decreased concentrations of albumin and globulin in blood profile"

Breed: Lundehund (Dog) (VBO_0200838).

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.

Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
