Inherited forms of ichthyosis, or generalized scaling of the skin, have been reported in many animal species, including cattle, and are characterized by an autosomal recessive mode of inheritance. We investigated 2 calves affected with ichthyosis fetalis, a Polled Hereford and a Shorthorn. Both cases had hard white plaques on the skin consistent with excessive keratinization. Read More

Background: Ichthyosis is a dermatological disease characterized by varying degrees of generalized hyperkeratosis and alopecia. Two congenital forms of ichthyosis are recognized in animals: fetalis (IF) and congenita. The disease occurs rarely in cattle, swine, dogs, chickens and a goat; it has not been reported in sheep.

Perinatal-lethal Gaucher disease is very rare and is considered a variant of type 2 Gaucher disease that occurs in the neonatal period. The most distinct features of perinatal-lethal Gaucher disease are non-immune hydrops fetalis. Less common signs of the disease are hepatosplenomegaly, ichthyosis and arthrogryposis. Read More

Gaucher disease, the inherited deficiency of the enzyme glucocerebrosidase, is the most common of the lysosomal storage disorders. Type 2 Gaucher disease, the most severe and progressive form, manifests either prenatally or in the first months of life, followed by death within the first years of life. The rarity of the many lysosomal storage disorders makes their diagnosis a challenge, especially in the newborn period when the focus is often on more prevalent illnesses. Read More

Harlequin color change is a distinctive cutaneous phenomenon presenting as a well-demarcated color change, with half of the body displaying erythema and the other half pallor. Only a few cases have been reported, possibly because of under-recognition. Recognition of this benign, self-limited condition may enable physicians to avoid unnecessary interventions. Read More

Ichthyosis fetalis or Harlequin ichthyosis is an extremely severe and fatal hereditary skin disorder with an autosomal recessive inheritance. It is distinctive because of its remarkable clinical appearance which includes epidermal keratinization, hypoplasia of fingers or nails, malformation of ear and nose and incompatibility with life. This report describes a case of Harlequin ichthyosis along with detailed autopsy findings, which manifested the suspended animation in the early hours after delivery and showing a peculiar malformation of the cerebral hemispheres.

Perinatal-lethal Gaucher disease is very rare and is considered a variant of type 2 Gaucher disease that occurs in the neonatal period. The most distinct features of perinatal-lethal Gaucher disease are non-immune hydrops fetalis, in utero fetal demise and neonatal distress. In some cases without hydrops, neurological signs occur in the first week of life and lead to death within 3 months. Read More

The widespread use of elite sires by means of artificial insemination in livestock breeding leads to the frequent emergence of recessive genetic defects, which cause significant economic and animal welfare concerns. Here we show that the availability of genome-wide, high-density SNP panels, combined with the typical structure of livestock populations, markedly accelerates the positional identification of genes and mutations that cause inherited defects. We report the fine-scale mapping of five recessive disorders in cattle and the molecular basis for three of these: congenital muscular dystony (CMD) types 1 and 2 in Belgian Blue cattle and ichthyosis fetalis in Italian Chianina cattle.

Case report on severe hypernatraemic dehydration in a non-recognised collodion baby who also suffered from hydrops fetalis caused by supraventricular tachycardia. Excessive transcutaneous fluid loss caused s-Na+ reaching 182 mmol/l within 36 hours of birth. The infant was cautiously rehydrated during the following three days. Read More

Mutations of the lamin B receptor (LBR) have been shown to cause HEM dysplasia in humans and ichthyosis in mice. LBR is a bifunctional protein with both a lamin B binding and a sterol Delta(14)-reductase domain. It previously has been proposed that LBR is the primary sterol Delta(14)-reductase and that HEM dysplasia and ichthyosis are inborn errors of cholesterol synthesis. Read More

The occurrence of ichthyosis in two Italian Chianina calves is described for the first time. Both animals, affected by ichthyosis fetalis and ichthyosis congenita, respectively, showed diffuse cutaneous thickening which had been present since birth. The first patient was a three-month-old female calf; inelastic leather cuirass-like skin associated with generalized hypotrichosis and local alopecia, delay of the physiologic change of coat colour, stiff movement and growth retardation were the most prominent clinical characteristics.

Gaucher disease, the inherited deficiency of glucocerebrosidase, is characterized by significant genetic and phenotypic heterogeneity. At the extreme end of the phenotypic continuum is the perinatal lethal variant, typically presenting in utero or during the neonatal period as hydrops and/orcongenital ichthyosis, with severe and progressive neurological involvement. Insights from the null-allele Gaucher mouse model contributed to the identification of this distinct phenotype, which has unique epidermal involvement. Read More

Gaucher disease, the most common lysosomal storage disorder, encompasses a wide spectrum of clinical symptoms. The perinatal lethal form is very rare and is considered a distinct form of classic type 2 Gaucher disease. Prominent features of the severe perinatal form are hepatosplenomegaly variable, associated with hydrops fetalis and ichthyosis. Read More

Gaucher's disease, the inherited deficiency of glucocerebrosidase, manifests with vast phenotypic variation. Even among patients with type 2 (acute neuronopathic) Gaucher's disease, there is a spectrum of clinical presentations. DNA samples from 14 patients with type 2 Gaucher's disease with a course ranging from intrauterine death at 22 wk of gestation to survival until age 30 mo were studied. Read More

Keratosis diffusa fetalis is a rare autosomic recessive disorder, in which infants are covered with large parchment-like scales, split by deep fissures. Most affected infants die a few weeks after birth because of infections and respiratory problems. The authors present the clinical, histological and ultrastructural aspects of two cases of Ichthyosis congenita fetalis observed in negro-African newborns. Read More

A group of neonates with Gaucher disease with a particularly devastating clinical course is described. The phenotype of these infants is analogous to that of a Gaucher mouse, which was created by targeted disruption of the mouse glucocerebroside gene. Similar to the homozygous mutant mice with glucocerebrosidase deficiency, these infants present at or shortly after birth, have rapidly progressing fulminant disease, and many have associated ichthyotic skin and/or hydrops fetalis.
