OMIA 000588-9615 : Lens luxation in Canis lupus familiaris

In other species: domestic cat

Possibly relevant human trait(s) and/or gene(s) (MIM number): 613195

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2010

Species-specific name: Primary lens luxation; isolated canine ectopia lentis

Species-specific symbol: PPL

Mapping: Sargan et al. (2007) conducted a genome scan with 364 microsatellites on "23 PLL-affected miniature bull terriers, together with an equal number of obligate PLL carriers with no luxation, and also 23 PLL-affected Lancashire heeler, with an equal number of obligate carriers with no luxation". A linkage analysis highlighted "a 6.3-Mbp region in the central part of chromosome 3".

By conducting a GWAS on 28 affected and 20 control Jack Russell Terriers, each genotyped with the CanineSNP20 BeadChip, Farias et al. (2010) highlighted the same region on chromosome CFA3 as identified by Sargan et al. (2008). Subsequent fine-mapping narrowed the region to a 664kb segment harbouring the positional candidate gene ADAMTS17.

Molecular basis: By sequencing the positional candidate gene ADAMTS17, Farias et al. (2010) identified the causal mutation as "a G→A transition at c.1473+1, which destroys the splice donor recognition site in intron 10".

Oliver et al. (2018): "All affected [Primary open-angle glaucoma (POAG), primary lens luxation (PLL), or both] Shar-Pei were homozygous for a 6-bp deletion in exon 22 of ADAMTS17 predicted to affect the resultant protein. All unaffected Shar-Pei were heterozygous or homozygous for the wild-type allele. The variant sequence was significantly associated with affected status (diagnosis of POAG, PLL, or both). All dogs of other breeds were homozygous for the wild-type allele. The cDNA sequencing confirmed presence of the expected variant mRNA sequence in ocular tissue from the affected dog only. Gene expression analysis revealed a 4.24-fold decrease in the expression of ADAMTS17 in ocular tissue from the affected dog."

Breeds: Chinese Shar-Pei, Jack Russell Terrier, Lancashire heeler, Miniature Bull Terrier.

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.
