OMIA:001342-8790 : Mucopolysaccharidosis IIIB in Dromaius novaehollandiae (emu) |
In other species: dog , pig , taurine cattle
Categories: Lysosomal storage disease
Links to possible relevant human trait(s) and/or gene(s) in OMIM: 252920 (trait) , 609701 (gene)
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Disease-related: yes
Key variant known: yes
Year key variant first reported: 2001
Cross-species summary: Also known as Sanfilippo syndrome type B
Molecular basis: Aronovich et al. (2001): "The two affected emus were found to be homozygous for a 2-bp deletion, 1098-1099delGG, in exon 6 [of NAGLU]. The resulting frameshift predicts a longer ORF of 2370 bp encoding a polypeptide with 37 additional amino acids and 387 altered amino acids. "
Prevalence: Genger et al. (2018): "Screening blood samples from 78 breeding emus revealed 14 (18%; 9 males, 4 females, one unknown gender) carriers; an overall .09 mutant NAGLU allele frequency."

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.
