Links to possible relevant human trait(s) and/or gene(s) in OMIM: 151670 (gene)

Single-gene trait/disorder: yes

Mode of inheritance: Autosomal recessive

Key variant known: yes

Year key variant first reported: 2026

Species-specific symbol: ATX

Molecular basis: Weber et al. (2026) investigated an inherited neuromuscular disorder in Brown Swiss cattle. Use of whole genome sequencing resulted in the identification of a "rare homozygous missense variant in LIPC (chr10:51715800G>C; NM_001035410.1:c.924C>G; p.Phe308Leu; omia.variant:1842) ... and in-silico predictions classified this variant as deleterious. Population-level genotyping of over 20.000 BS cattle revealed a variant allele frequency of 17% with significant deviation from the Hardy–Weinberg equilibrium (p-value=1.14 × 10⁻20), suggesting possible lethality in homozygotes. "

Clinical features: Weber et al. (2026):  Affected Brown Swiss animals "exhibited consistent neurological signs, including postural deficits and subconscious proprioceptive ataxia. Biochemical profiles revealed hypercholesterolemia, hypertriglyceridemia, and decreased HDL cholesterol, suggesting dyslipidemia."  

Breed: Brown Swiss (Cattle) (VBO_0000166).

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.
