Molecular Genetics

Kunz et al. (2016) reported a likely causal mutation as "a missense mutation (p.S568N, c.G1703A; [Chr4: 49,878,773 bp, rs800397662]) in the PNPLA8 gene that encodes patatin-like phospholipase domain containing 8".

Genetic Test

Using the powerful tool of imputation from 50K SNP genotypes, McClure et al. (2013) reported that <7,500 Brown Swiss have now been characterised as carriers or non-carriers of the haplotype described in the Mapping section (above). Identification of a likely causal mutation by Kunz et al. (2016) (see Molecular basis section) has the potential to replace the haplotype test with a specific SNP test.
