OMIA:002298-9913 : Neuropathy with splayed forelimbs, UCHL1-related in Bos taurus (taurine cattle)
Categories: Nervous system phene
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2022
Species-specific name: Jersey neuropathy with splayed forelimbs
Species-specific symbol: JNS
Species-specific description: In a press release issued on 20 November 2020, the American Jersey Cattle Association announced that "A new undesirable genetic factor, known as Jersey Neuropathy with Splayed Forelimbs (JNS), has been identified in the Jersey breed."
Inheritance: Al-Khudhair et al. (2022): "Inheritance of an undesirable genetic factor was determined from a study of 16 affected calves reported by Jersey breeders across the United States. All of their pedigrees traced back on both paternal and maternal sides to a common ancestor born in 1995."
Mapping: Al-Khudhair et al. (2022): "Genotypes revealed that JNS is attributable to a specific haplotype on Bos taurus autosome 6."
Molecular basis: Al-Khudhair et al. (2022): "Sequencing of the region of shared homozygosity revealed missense variant rs1116058914 at base 60,158,901 of the ARS-UCD1.2 reference map as the most concordant with the genetic condition and the most likely cause. The single-base G to A substitution is in the coding region of the last exon of UCHL1, which is conserved across species."
Have human generated variants been created, e.g. through genetic engineering and gene editing
Clinical features: Al-Khudhair et al. (2022): "Calves affected with JNS are unable to stand on splayed forelimbs that exhibit significant extensor rigidity and excessive lateral abduction at birth. Affected calves generally are alert at birth but exhibit neurologic symptoms, including spasticity of head and neck and convulsive behavior. Other symptoms reported include dislocated shoulders, congenital craniofacial anomalies, and degenerative myelopathy."
Prevalence: Al-Khudhair et al. (2022): "Currently 8.2% of the genotyped US Jersey population are carriers of the haplotype."

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.
