...Alanood N. AlKhas; Ali H. Ziyab Introduction: Psoriasis is caused by an interplay between intrinsic and extrinsic factors. Parental consanguinity increases homozygosity in the genome of the offspring, which in turn increases disease risk. The association between parental consanguinity and psoriasis...

...Fatemeh Keyfi; Mojila Nasseri; Samira Nayerabadi; Amin Alaei; Armin Mokhtariye; Abdolreza Varasteh Objective: Inborn errors of metabolism (IEMs) are disorders with various manifestations that occur mainly in the pediatric population. In countries where consanguineous marriage is common...

... and the role of many genes within the genome. The opportunity for the discovery of extremely rare autosomal recessive causes of ocular abnormalities from the study of consanguineous families is large, particularly through the powerful combination of next-generation sequencing with autozygosity mapping. Having...

... of consanguinity, show that truly ambiguous genitalia have an estimated incidence of 1:5,000 births. There are indications that the prevalence of DSD is higher in endogamous communities. The incidence of ambiguous genitalia in Saudi Arabia has been estimated at 1:2,500 live births; whilst in Egypt, it has been...

... of Arabian origin or Bedouins, those from an Eastern or Persian ancestry and individuals with African admixture. Historically, all types of consanguineous marriages have been and still are common in the Qatari population, particularly among first and double-first cousins. Thus, there is a higher risk...

...Peter C. Corry Objectives: The aim of this paper is to describe the current knowledge about inherited diseases in UK children of Pakistani origin, who now number over 300,000, and to investigate disease associations with parental consanguinity. Methods: Published data on the overall prevalence...

...Hussein A. Abbas; Khalid Yunis Consanguineous marriages constitute a significant fraction of marriages worldwide and confer a major public health concern on newborns. In addition to the risk of acquiring a recessive genetic disease, the offspring of consanguineous parents are plausibly...

...Leo P. ten Kate; Marieke E. Teeuw; Lidewij Henneman; Martina C. Cornel This paper reviews what is currently known about the presence of consanguinity and endogamy in the Netherlands, in the past and today, and concludes with a discussion of medical genetic aspects. First geographic characteristics...

...Ibrahim M. Gosadi; Elizabeth C. Goyder; Marion D. Teare Objective: To examine mechanisms by which consanguinity might increase the risk of type 2 diabetes (T2D) in a Saudi population. Methodology: 362 adult male participants were recruited, 179 were T2D patients and 183 healthy siblings. T2D...

... are inherited in an autosomal recessive pattern; therefore, they are more common in areas with high rates of consanguineous marriage. Reports about PIDs from these areas have demonstrated a peculiar prevalence of more severe forms of diseases compared to other regions, and patients born to consanguineous...

... storage disease caused by a deficiency of arylsulfatase B. However, in Monte Santo, a poor and isolated rural region in Northeast Brazil with large family sizes and high rates of community endogamy and parental consanguinity (α = 0.00483), 9 living and 4 now deceased individuals in 11 kindreds have been...

...Kristen Lipscomb Sund; Catherine Weaver Rehder The detection of consanguinity by the presence of multiple regions of homozygosity (ROH) is not an uncommon occurrence in clinical laboratories performing SNP microarray analysis. Reporting practices amongst laboratories are highly variable, due...

...Khalid Al-Thihli; Fathiya Al-Murshedi; Nadia Al-Hashmi; Watfa Al-Mamari; M. Mazharul Islam; Said A. Al-Yahyaee The Sultanate of Oman, like many other Arab countries, has relatively high rates of consanguinity. Reports suggest that the incidence of inborn errors of metabolism (IEM) is also high...

... values and beliefs, with the family accepted as the central structure of society. Consanguineous marriage is favored and respected in most if not all Arab communities, and intrafamilial unions currently account for 20-50% of all marriages. First-cousin unions are especially popular and constitute almost...

...Meimanat Hosseini-Chavoshi; Mohammad J. Abbasi-Shavazi; Alan H. Bittles Objectives: The aims of the study were to determine the prevalence, types and socio-economic correlates of consanguineous marriages in Iran, and to gauge the extent to which consanguinity influenced fertility, pregnancy...

..., Tunisia is a North African country of 11 million inhabitants. Throughout its history, it has been invaded by different ethnic groups. These historical events, and consanguinity, have impacted on the spectrum and frequency of genetic diseases in Tunisia. Investigations of Tunisian families have...

...Trevor J. Pemberton; Noah A. Rosenberg Background/Aims: Culturally driven marital practices provide a key instance of an interaction between social and genetic processes in shaping patterns of human genetic variation, producing, for example, increased identity by descent through consanguineous...

... to seek new genes responsible for the disease, we studied a consanguineous Italian family through exome sequencing combined with homozygosity mapping. Six missense homozygous variants passed our filtering selection and at least two of them were associated with some aspects of the pathological phenotype...

... these, the FA2H mutation remained the only plausible one. Conclusion: In single consanguineous pedigrees with a few affected sibs, EX-HOM can be a one-step approach to identify the candidate genetic defect, bypassing obstacles such as genetic heterogeneity and the need for large pedigrees.
