Linkage of combined factors V and VIII deficiency to chromosome 18q by homozygosity mapping.
Combined Factors V and VIII deficiency is an autosomal recessive bleeding disorder identified in at least 58 families comprising a number of different ethnic groups. Affected patients present with a moderate bleeding tendency and have Factor V and Factor VIII levels in the range of 5-30% of normal. The highest frequency of the mutant gene is found in Jews of Sephardic and Middle Eastern origin ...
متن کاملHomozygosity mapping of a Desbuquois dysplasia locus to chromosome 17q25.3.
Desbuquois dysplasia is a rare autosomal recessive chondrodysplasia characterised by short stature, joint laxity, facial dysmorphism, a "Swedish key" appearance of the proximal femur, advanced carpal and tarsal bone age, and hand anomalies consisting of phalangeal dislocations and an extra ossification centre distal to the second metacarpal. However, the latter changes are not consistently obse...
متن کاملHomozygosity mapping of achromatopsia to chromosome 2 using DNA pooling.
Achromatopsia is an autosomal recessive disease of the retina, characterized clinically by an inability to distinguish colors, impaired visual acuity, nystagmus and photophobia. A genome-wide search for linkage was performed using an inbred Jewish kindred from Iran. To facilitate the genome-wide search, we utilized a DNA pooling strategy which takes advantage of the likelihood that the disease ...
متن کاملLocalisation of pseudohypoaldosteronism genes to chromosome 16p12.2-13.11 and 12p13.1-pter by homozygosity mapping.
Pseudohypoaldosteronism type 1 (PHA1, OMIM 264350) is a rare Mendelian disorder characterised by end-organ unresponsiveness to mineralocorticoids. Most steroid hormone insensitivity syndromes arise from mutations in the corresponding receptor, but available genetic evidence is against involvement of the mineralocorticoid receptor gene, MLR, in PHA1. A complete genome scan for PHA1 genes was und...
متن کاملHomozygosity and linkage disequilibrium.
We illustrate how homozygosity of haplotypes can be used to measure the level of disequilibrium between two or more markers. An excess of either homozygosity or heterozygosity signals a departure from the gametic phase equilibrium: We describe the specific form of dependence that is associated with high (low) homozygosity and derive various linkage disequilibrium measures. They feature a clear ...
