Studies of the quantitative genetics of natural populations have contributed greatly to evolutionary biology in recent years. However, while pedigree data required are often uncertain (i.e. incomplete and partly erroneous) and limited, means to evaluate the effects of such uncertainties have not been developed. We have therefore developed a general framework for power and sensitivity analyses o...
Juvenile myoclonic epilepsy (JME), the most common genetic epilepsy, remains enigmatic because it is considered one disease instead of several diseases. We ascertained three large multigenerational/multiplex JME pedigrees from Honduras with differing JME subsyndromes, including Childhood Absence Epilepsy evolving to JME (CAE/JME; pedigree 1), JME with adolescent onset pyknoleptic absence (JME/p...
Characterization of short root anomaly in a Mexican cohort--hereditary idiopathic root malformation.
OBJECTIVE The purpose of this study was to systematically characterize individuals with short root anomaly (SRA) without any history of orthodontic treatment. The long-term objective of the study was to improve diagnosis and treatment planning and determine risk factors for developing SRA. SETTING AND SAMPLE POPULATION Twenty-seven patients including two families and 16 unrelated individuals ...
pedigree information of iranian holstein dairy cattle, collected via animal breeding centre of iran from 1971 to 2007, were utilized to describe the reasons for the increasing inbreed coefficient. inbreeding coefficient (f) and pedigree completeness (pci) of all the available cattle were found out using a pedigree structure of 883713 animals. the herds with pci of above 0.85 were picked out and...
Pedigree problems are typical tasks in school genetics classes. However, they perceived as difficult and often not successfully completed. Therefore, the purpose of this study is to determine relevant factors that might have an impact on success pedigree analysis. Based previous research, we investigate influence superficial appearance (relating a well-known misconception), mode inheritance, co...
was thought to be more common than ARMD, BMD remained a signficant possibility. When RFLP technology became really powerful, with the identification of flanking markers to the BMD locus, I decided to apply it to this diagnostic problem. The findings argued against BMD. The table compares the probabilities of the RFLP findings, CK readings, and pedigree pattern on the assumption that the sisters...
A 5-year-old child with Crouzon's disease presented with luxation of the eyeballs and advanced endophthalmitis as a result of which both the eyes had to be enucleated. This case led us to study the family pedigree. The factors influencing the pattern of clinical presentation, and hence the ultimate treatment of orbital disease, are discussed. The case is presented to emphasise the different con...
Abstract An O(nmα(m)) time algorithm is given for inferring haplotypes from genotypes of non-recombinant pedigree data, where n is the number of members, m is the number of sites, and α(m) is the inverse of the Ackermann function. The algorithm works on both tree and general pedigree structures with cycles. Constraints between pairs of heterozygous sites are used to resolve unreso...
