family studies suggest that there is a strong genetic component to the etiology of comitant strabismus. seven cases of a family in three consecutive generations found to have isolated comitant exotropia. this pattern of inheritance is highly suggestive of an autosomal-dominant mode with complete penetrance which is an unreported finding in this entity.   iranian journal of ophthalmology 200921(...

lamellar ichthyosis is one form of congenital autosomal recessive ichthyosis. to date, seven causative genes for arci have been identified. to understand further the genetic spectrum of the disease, we analyzed a four-generation iranian family with arci that had observable inheritance. exome sequencing data for one of the affected individuals with ichthyosis from a consanguineous iranian family...

in order to increase drought tolerance in bread wheat, an appropriate breeding program based on inheritance of drought tolerance is recommended. in the present study, nine bread wheat cultivars and their f2 progenies were evaluated in a randomized complete block design under normal and drought stress conditions. nine sensitivity/tolerance indices were calculated for studied genotypes and stress...

OBJECTIVE To describe the clinical features of ocular melanosis in Cairn Terriers. ANIMAL STUDIED One hundred and fourteen Cairn Terriers diagnosed with ocular melanosis. PROCEDURES A complete eye examination was performed on each dog. Four dogs (and two unaffected control dogs) underwent a high frequency ultrasound examination of the anterior segment. The pedigrees of affected dogs were an...

The development of a practical screening procedure for phenylketonuria and the improvement in methods of chemical analysis have led to a realization that Folling's (1934) disease of phenylketonuria is not a single entity. In this commentary, the current view on some aspects of phenylketonuria will be reviewed and the problems illustrated by experience gained in the Phenylketonuria Clinic at the...

The authors administered inventories of vocational and recreational interests and talents to 924 pairs of twins who had been reared together and to 92 pairs separated in infancy and reared apart. Factor analysis of all 291 items yielded 39 identifiable factors and 11 superfactors. The data indicated that about 50% of interests variance (about two thirds of the stable variance) was associated wi...

Continuing uncertainty about the etiology of schizophrenia calls for periodic reappraisal of relevant data and conclusions, reappraisals guided by a beacon of modest doubt to avoid the distorted views of both the zealot and the skeptic. This review does not set out to cover every possible aspect of the genetics of schizophrenia. It deals with data from recent family, twin, and adoption studies ...

A substantial part of the contribution of genetic studies to the treatment of schizophrenia involves its emphasis on reliable and valid diagnoses. One consequence of this focus is the recognition that schizophrenic illness is broader than the diagnostic entity of schizophrenia itself, and instead consists of a "spectrum" of related disorders. Because some of the symptoms in these disorders diff...
