Species-specific name: Ichthyosis fetalis

Species-specific symbol: IF

Mapping: In a pioneering use of tens of thousands of SNP markers ("using either the 25K Affymetrix SNP panel or a custom-made 60K Illumina panel"), Charlier et al. (2008) identified a single 11.78 Mb region on BTA2 in which 3 affected calves were significantly more homozygous for the same allele at each of many SNPs, when compared with 9 normal controls. An investigation of comparative candidate genes in this region identified the ABCA12 gene as a likely culprit. This gene encodes the 12th member of the A subfamily of ATP-binding cassette transporters. Some sequencing of this gene quickly identified the molecular lesion.

Molecular basis: In the words of Charlier et al. (2008): "a missense mutation in exon 39 (A5804G) resulting in an H1935R substitution in the fourth extracellular loop". The His (normal) form of the peptide is conserved in all vertebrates sequenced to date. (FN 080330)

Clinical features: In the words of Charlier et al. (2008), "Affected calves show cutaneous lesions, with deep fissures separating hyperkeratotic skin plaques and eversion of mucocutaneous junctions (ectropion and eclabium), reminiscent of harlequin ichthyosis in humans".

Prevalence: O'Rourke et al. (2017) reported that "The known mutation (H1935R) in gene ABCA12, responsible for ichthyosis fetalis in Chianina cattle, was shown to be absent in . . . [one Polled Hereford and one Shorthorn affected calf] and their obligate heterozygous parents. "
