Acrocallosal syndrome in a girl born to consanguineous parents.

The present report describes on a 1-year-old girl with macrocephaly, bulging forehead, ocular hypertelorism, antimongoloid palpebral slant, convergent strabismus, atrophy of optic papillae, short philtrum, protruding lips, high-arched palate, bifid uvula, broad trunk, apparently widely spaced nipples, diastasis recti, small umbilical hernia, tapering fingers, fifth-finger clinodactyly, postaxial polydactyly of the left hand, and bilateral hallux duplication. Partial agenesis of the corpus callosum and central diffuse cortical cerebral atrophy was documented on computed tomography. Chromosomes were normal. Parents were related as half first cousins. Their previous pregnancy had ended in a miscarriage. We suggest that this patient has an acrocallosal syndrome inherited as an autosomal recessive trait. This supports other recent reports that have considered this entity to differ from Greig cephalopolysyndactyly.

TAR-like syndrome in a consanguineous Mayan girl.

We report on a 3-month-old girl with a TAR-like syndrome. Her older brother died with a similar disorder at 3 months of unknown causes. The parents are second cousins of Mayan ancestry. The infant also had, in addition to the usual abnormalities of TAR syndrome, depressed nasal bridge, cataracts, glaucoma, megalocorneae, and blue sclerae.

Polydactyly, campomelia, ambiguous genitalia, cystic dysplastic kidneys, and cerebral malformation in a fetus of consanguineous parents: a new multiple malformation syndrome, or a severe form of oral-facial-digital syndrome type IV?

We describe a 27-week fetus with occipitoschisis, polydactyly, campomelia, cleft palate, laryngeal dysplasia, ocular colobomata, hepatic fibrosis and intrahepatic cyst, ambiguous genitalia, cystic dysplastic kidneys, and brain malformation. This pattern of abnormalities appears unique. The differential diagnosis is discussed. The parents are first cousins, making autosomal recessive inheritance likely.

Amelia of the arms and femur/fibula deficiency with splenogonadal fusion in a child born to a consanguineous couple.

A male infant was born with symmetrical tetramelic limb deficiency consisting of bilateral upper limb amelia with severe symmetrical proximal focal femoral deficiency and fibula deficiency associated with left splenogonodal fusion of the discontinuous type, micrognathia, and a prominent capillary haemangioma of the face. The parents are first cousin Lebanese muslims. This observation suggests the possibility of recessive inheritance in some cases of the Amelia, Femur-Fibula dysostosis syndrome with or without splenogonadal fusion.

Effects of consanguinity, exposure to pregnant females, and stimulation from young on male gerbils' responses to pups.

In three experiments investigating variables affecting responses of male Mongolian gerbils to conspecific young, we compared the behavior directed towards pups of natural fathers, virgin foster fathers, and sexually experienced foster fathers (Experiment 1); males either previously exposed or not exposed to pregnant females (Experiment 2); and males provided or not provided with extra opportunities to huddle over pups (Experiment 3). We found no difference in responses to pups among natural fathers, virgin foster fathers, and foster fathers that had fathered litters. On the other hand, both a week of exposure to a pregnant female and opportunity to huddle over pups for an extra 15 min/day had significant effects on males' subsequent responses to conspecific young. We speculate on the reasons why a male's response to pups might be affected by his exposure to a pregnant female and stimuli from pups, but not by the probability that the pups were his own offspring.

Determining consanguinity by oligonucleotide fingerprinting with (GTG)5/(CAC)5.

Simple tandemly organized (GTG)n/(CAC)n sequences are spread throughout the human chromosomes. The most informative DNA fingerprints for the testing of pedigrees and/or paternity were obtained with the simple triplet repeat probe (GTG)5 or its complement (CAC)5. These hypervariable simple-repeat fragments are stably inherited in a Mendelian fashion. Using these highly discriminating probes, all human individuals could, theoretically, be differentiated, except for genetically identical monozygotic twins. Examples from actual case work are reported and pertinent advantages of this methodology are discussed.

Consanguinity and multiple sclerosis in Orkney.

For all patients with multiple sclerosis in Orkney who were alive in 1974 or who had died during 1958 to 1974, pedigree data were analysed. The relationship between their parents, expressed by kinship coefficients, was compared with that between parents of matched controls. The closer relationship between parents of patients suggests that it is the genes that are shared by a patient's parents, and that he inherits from both, that influence his susceptibility to multiple sclerosis.

Interactive visual analysis of SNP data for rapid autozygosity mapping in consanguineous families.

Autozygosity mapping of recessive disorders using small numbers of highly inbred families is a powerful tool for disease gene identification. With the advent of cheap rapid methods for whole-genome SNP genotyping, data analysis, rather than laboratory work, has become rate-limiting for this approach. Here, we describe AutoSNPa, a computer program used for handling and visually presenting large amounts of SNP data, in such a way as to facilitate the rapid identification and subsequent scrutiny of autozygous regions.

Hypomandibular faciocranial dysostosis in consanguineous parents revealed by ultrasound prenatal diagnosis.

We report here the fourth case of hypomandibular faciocranial dysostosis (HFD). The diagnosis was made at birth on the association of severe retrognathia, microstomia, severe hypoglossia with glossoptosis, persistent buccopharyngeal membrane, median cleft palate, bifid uvula, down-slanting palpebral fissures, short nose with anteverted nares, laryngeal hypoplasia, and low-set ears. A severe microstomia and micrognathia were detected by ultrasound at 31 weeks of gestation. Interestingly, even though the present case exhibits many facial dysmorphic features characteristic of HFD, craniosynostosis was absent. This report suggests that craniosynostosis is not mandatory for the diagnosis of this condition. Furthermore, we present a new argument for an autosomal recessive mode of inheritance for HFD.
