Cross-species summary: Renamed from Musladin-Lueke syndrome [3/6/2022]

Species-specific name: Musladin-Lueke syndrome, Chinese beagle syndrome

Species-specific symbol: MLS

History: As reported by Bader et al. (2010), this disorder was "originally called “Chinese beagle syndrome” in the lay literature, and subsequently renamed after two noted beagle breeders, Musladin and Lueke"; see Musladin et al. (1990, 1998).

Mapping: By conducting a genome scan on 6 affecteds and 39 control Beagles, each genotyped for 719 microsatellites in a case-control design, Bader et al. (2010) mapped the disorder to a region on chromosome CFA9.

Molecular basis: Fine-mapping followed by sequencing of likely positional candidate genes resulted in Bader et al (2010) identifying the causal mutation as a missense mutation in ADAMTSL2: "(c.660C>T) predicted a non-synonymous change, converting an arginine to a cysteine at codon 221 (R221C), occurred in a highly conserved stretch of residues, and was computationally predicted to negatively impact protein structure and function". The publication of Bader et al. 2010 probably had an incorrect numbering of the cDNA in their variant designation. The correct variant designation should read XM_003639308.3:c.661C>T; p.Arg221Cys.

Clinical features: As reported by Bader et al. (2010), this disorder "is characterized by short stature, thick, taut skin, and severely restricted joint mobility . . . Affected dogs also have broad skulls with wide-set slanted eyes, creased ears, a hopping, “tip-toe” gait, and pleasant temperaments." Additionally, cardiac disease has been reported as possibly associated with Muscladin-Lueke syndrome, but reports are inconsistent (Packer et al., 2017).

Variants

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.
