Zhang et al. (2019): "Normally IH begins with a small and painless protrusion of the interdigital skin which sometimes can already be diagnosed at calf age. In the final stage clinical signs of IH are firm tumor like masses found in the interdigital space with skin lesions that can result in deep necrosis and phlegmonous inflammations."

Besser et al. (1990) reported a congenital syndrome of long, thin limbs, severe joint and tendon laxity, microspherophakia, ectopia lentis, heart murmurs and aortic dilatation in 7 calves, where all sired by a single phenotypically normal bull suspected of germline mosaicism for a new mutation resulting in this disease. One of the calves died with ruptured aorta at age 16 months. Histopathologic and electron microscopic studies of the aortic m...

Reith et al. (2024): "Whole-genome sequencing (WGS) of 7 blind cattle and 9 unaffected relatives revealed a 1-bp frameshift deletion in ceroid lipofuscinosis neuronal 3 (CLN3; chr25 g.26043843del) for which the blind cattle were homozygous and their parents heterozygous. The identified variant in exon 16 of 17 is predicted to truncate the encoded protein (p. Pro369Argfs*8) ... ."
