BACKGROUND Primary ciliary dyskinesia (PCD) is a rare, genetically heterogeneous ciliopathy disorder affecting cilia and sperm motility. A range of ultrastructural defects of the axoneme underlie the disease, which is characterised by chronic respiratory symptoms and obstructive lung disease, infertility and body axis laterality defects. We applied a next-generation sequencing approach to ident...

Objective(s): Genetic analysis of two consanguineous Pakistani families with localized autosomal recessive hypotrichosis was performed with the goal to establish genotype-phenotype correlation. Materials and Methods: Genomic DNA extraction had been done from peripheral blood samples. Extracted DNA was then subjected to PCR (polymerase chain reaction) for amplification. Linkage analysis was perf...

An enquiry answered by 100 randomly selected British Pakistani mothers in the postnatal wards of two hospitals in West Yorkshire showed that 55 were married to their first cousins, while in only 33 cases had their mother been married to her first cousin. This suggests an increasing rate of consanguineous marriage in this relatively small group, by contrast with the decreasing rate observed in s...

The occurrence of cystic fibrosis is very rare in the Asian population. Carriers of the mutations most commonly found in Caucasians were not detected in a large Asian population sample of almost 900 chromosomes. However, an affected Pakistani child born to consanguineous parents was further investigated and shown to be homozygous for the mutation S549N (G-->A). Molecular and clinical data are p...

To analyze the influence of consanguinity and maternal education on stillbirth and infant death for children born in Norway between 1967 and 1993, the authors studied 7,274 children of ethnic Pakistani origin and 1,431,055 children of Norwegian ethnic origin. Of these children, 31.0% of the Pakistani children and 0.1% of the Norwegian children had parents who were first cousins. Consanguinity i...

Mutations in the estrogen-related receptor beta (ESRRB) gene is the underlying cause of autosomal recessive nonsyndromic hearing impairment (ARNSHI) due to the DFNB35 locus which maps to 14q24.3. A genome scan of a large consanguineous Pakistani pedigree with ARNSHI established linkage with a maximum multipoint LOD score of 4.2 to the 14q24 region and the region of homozygosity contained the ES...

BACKGROUND Congenital insensitivity to pain (CIP) (OMIM 243000) is a rare autosomal-recessive disorder. Clinically, CIP is characterized by insensitivity to all modalities of pain except neuropathic pain, and recurrent injuries frequently go unnoticed. CIP is caused by mutations in the SCN9A gene encoding for the Na1.7 channel. METHODS We analyzed the DNA from members of a consanguineous Paki...

In July 2011, a 1.82-kg full-term male was delivered by caesarean section at a regional hospital. The parents were a consanguineous Pakistani couple and this was their firstborn. At birth, the baby exhibited generalised ruptured bullae (Fig 1), but there was no family history of any bullous disorder. The boy’s nails were not dystrophic. New blisters continued to develop spontaneously, without a...

PURPOSE To identify the disease-causing mutations in three consanguineous Pakistani families with multiple members affected by primary congenital glaucoma. METHODS Blood samples were collected, and DNA was extracted. Linkage analysis for reported primary congenital glaucoma loci was performed using closely spaced polymorphic microsatellite markers on genomic DNA from affected and unaffected f...
