Cross-species summary: A lysosomal storage disease in which there is a buildup (storage) of GM1 gangliosides (a type of glycolipid) in various tissues, due to the lack of the enzyme beta-galactosidase, whose task is to break down the GM1 ganglioside into its constituents. Characterised by progressive neuromuscular dysfunction and impaired growth from an early age.

Molecular basis: A Genome-Wide Association Study (GWAS) for this disorder led Walker et al. (2012) to a region on chromosome OAR19 which is homologous to the region of human chromosome HSA3 that includes the candidate gene for this disorder, namely GLB1 which encodes β-galactosidase. Subsequent sequencing of the candidate gene by the same authors identified "a G to T base pair substitution mutation in exon 6 of ovine GLB1 causing a cysteine to phenylalanine amino acid substitution". Ahern-Rindell (2018) reported what could be the same variant: "A missence mutation has been found in exon 6 of the affected sheep’s beta-gal gene resulting in the loss of a cysteine residue possibly leading to the synthesis of an altered structural beta-gal but with detectable levels of protein product confirmed by Western Blotting."

Breed: Romney Marsh (Sheep) (VBO_0001582).

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.
