Background and Objective: Consanguinity increases the incidence of genetic disorders. The frequency of consanguinity varies in different societies. There was no data regarding the frequency of consanguinity in Zanjan province. This study aimed to describe the prevalence of consanguineous unions in the parents of children with genetic disorders and its related factors in Zanjan, Iran. Materials...

Missing genotype data can increase false-positive evidence for linkage when either parametric or nonparametric analysis is carried out ignoring intermarker linkage disequilibrium (LD). Previously it was demonstrated by Huang et al. [1] that no bias occurs in this situation for affected sib-pairs with unrelated parents when either both parents are genotyped or genotype data is available for two ...

The clinical and pathological features of two sisters born from consanguineous parents and affected by the rare Schwartz-Jampel syndrome are reported. The parental consanguinity of these two patients and the findings of electromyographic changes in the mother strongly support an autosomal recessive pattern of inheritance. No response of growth hormone secretion to arginine and insulin stimulati...

102 families of schizophrenic patients were studied by drawing pedigree charts. The affected relatives failed to manifest any sexwise difference and so were the probands. Parental consanguinity doesn't seem to augment positive family history. When Slater's computational model was applied to assess the mode of inheritance, the study favoured polygenic hypothesis.

1: The evidence base for intervention with respect to smoking and consanguinity. Meta-analyses reveal that passive smoking and consanguinity ARE both risk factors in OFC.

Background Consanguinity has been suggested as a risk factor for the development of schizophrenia in offspring in some Middle Eastern countries. Aim The purpose of this study was to review the frequency, pattern of parental consanguinity, and family history of schizophrenia among schizophrenia patients in Qatar, and to determine their impact on the associated risk factors. Design This is a cros...

A family with two sibs suffering from idiopathic infantile scoliosis associated with bilateral paralysis of conjugate gaze is reported. Although the parental consanguinity and the involvement of patients of both sexes in this family are suggestive of an autosomal recessive mode of inheritance, a dominant or multifactorial pattern remains a possibility.

In this study the clinical and epidemiological characteristics of congenital adrenal hyperplasia were evaluated prospectively in 47 patients admitted in Imam Reza Hospital in Mashhad during a 4 year period. 21-hydroxylase deficiency was present in 42 patients (89.3%), the simple virilizing form in 6 and the salt-losing form in 36 of them. 11b hydroxylase deficiency was present in 5 patient...

Anterior encephalocele (AE) is a rare congenital malformation in the central nervous system with a reportedly high prevalence in Assam, Northeast India. As there exists substantial variations in the etiology of the disease, determination of risk factors and timely intervention could reduce associated morbidity. A retrospective chart review of patients with AE who were born at or referred to Ass...
