Lamellar ichthyosis or congenital ichthyosiform erythrodema). In around 10% of cases the baby sheds this layer of skin and has normal skin for the rest of its life. This is known as "self-healing collodion baby". The remaining 15% of cases are caused by a variety of diseases involving keratinization disorders. Known causes of collodion baby include ichthyosis vulgaris and trichothiodystrophy. Less well documented causes include Sjögren-Larsson syndrome, Netherton syndrome, Gaucher disease type 2, congenital hypothyroidism, Conradi syndrome, Dorfman-Chanarin syndrome, ketoadipiaciduria, koraxitrachitic syndrome, ichthyosis variegata and palmoplantar keratoderma with anogenital leukokeratosis. Since many of these conditions have an autosomal recessive inheritance pattern, they
Henneke horse body condition scoring system to either being overweight or underweight, respectively. Breeding mares with a body condition score less than five have been linked in research to problems with reproduction.

Also, a mare with a body condition score less than five will have more difficulty conceiving. For these reasons, recommendations are for breeding mares to score between 6 and 7. Higher body condition scores have not been shown to affect reproduction but are unhealthy for the horse. Stallions have the best reproductive success at
