title: [Hypotrichosis and oligodontia, combined with an Xq-deletion, in a calf of the Swiss Holstein breed].
abstract: Hypotrichosis and oligodontia associated with a chromosomal anomaly (Xq-deletion) are described in a 11-month old cattle (Simmenthal/Red Holstein cross-breed). This chromosomal anomaly was accompanied with hairlessness and grievous teeth abnormalities. The animal had a very thin haircoat, had only one incisor and between one to three molars per mandible or maxilla. This resulted in reduced food intake, reduced rumination, and retarded growth. Post-mortem examination revealed lesions in the kidneys (bilateral chronic interstitial nephritis), adrenals (hyperplasia), pancreas (focal fibrosis) and abomasum (obstipation and multiple ulcers). Some of these abnormalities are comparable with the human "anhidrotic ectodermal dysplasia" (Christ-Siemens-Touraine syndrome) and supports the hypothesis that there are homologies in the X-chromosome of different mammals.
