Familial myelodysplastic syndrome occurring at a young age is a very rare childhood haematological malignancy. Two siblings, aged three and 18 years, from a consanguineous marriage, presented with pancytopenia and was subsequently diagnosed to have myelodysplastic syndrome. Both remained clinically stable throughout the illness. Splenectomy appeared to have fully corrected the cytopenia in one ...

We present a 15 year old boy who was born out of a non consanguineous marriage, and presented with bilateral cryptorchidism, mental retardation, facial dysmorphism, hypergonadotrophic hypogonadism with failure of anatomical and biochemical localisation of testes. Karyotype analysis showed 46 XY with inverted duplication on chromosome 5q22-31.

There is little information on inbreeding during the critical early years of human existence. However, given the small founding group sizes and restricted mate choices it seems inevitable that intrafamilial reproduction occurred and the resultant levels of inbreeding would have been substantial. Currently, couples related as second cousins or closer (F ≥ 0.0156) and their progeny account for an...

Two boys with bilateral agenesis of kidneys and ureters were the product of a consanguineous marriage. This family and previous reports of familial bilateral renal agenesis support the supposition that a minor proportion of cases of BRA is caused by the homozygous state of an autosomal recessive gene.

An 11-yr-old girl, born out of a consanguineous marriage presented with recurrent exertional syncope due to ventricular tachycardia. She had woolly hair, palmoplantar hyperkeratosis and mild cardiomegaly. Echocardiogram revealed mild left ventricular dysfunction. Features were consistent with Carvajal variant of Naxos disease, an arrhythmogenic cardiomyopathy with autosomal recessive inheritance.

An 8 year old boy was presented for difficulty in walking and muscle weakness with difficulty in climbing stairs, running and particularly in vigorous physical activities, he also had decreased strength and endurance. His parents did not have consanguineous marriage, one brother and two sisters were all healthy; no other family members were similarly affected.

These selected respondents reported a very high incidence of first-cousin marriages in their families. A smaller proportion of marriages were with more distant cousins, but Pearson remarked that second and third cousins in these families were also often related in more than one line. He lumped them all together and concluded that 'consanguineous marriages in the professional classes probably oc...
