Mixed Model Association with Family-Biased Case-Control Ascertainment.
Mixed models have become the tool of choice for genetic association studies; however, standard mixed model methods may be poorly calibrated or underpowered under family sampling bias and/or case-control ascertainment. Previously, we introduced a liability threshold-based mixed model association statistic (LTMLM) to address case-control ascertainment in unrelated samples. Here, we consider famil...
متن کاملMixed model with correction for case-control ascertainment increases association power.
We introduce a liability-threshold mixed linear model (LTMLM) association statistic for case-control studies and show that it has a well-controlled false-positive rate and more power than existing mixed-model methods for diseases with low prevalence. Existing mixed-model methods suffer a loss in power under case-control ascertainment, but no solution has been proposed. Here, we solve this probl...
متن کاملAssociation of Melasma with Thyroid Autoimmunity: A Case-Control Study
Introduction: Melasma is a common acquired hypermelanosis seen mainly in women which occurs on the sun-exposed skin of the face. The exact cause of melasma is unknown. The majority of the cases are attributed to pregnancy, combined oral contraceptive pills, genetic factors, sun exposure, use of cosmetic products, thyroid disorders and anti-convulsant drugs. This study was performed to evaluate ...
متن کاملAssociation of Melasma with thyroid disorders: A case-control study
Background and aim: Melasma is an acquired, symmetric hyperpigmentation, specially in sun-exposed skin. Disorders of thyroid gland result from processes that stimulate the overproduction or underproduction of thyroid hormones. This study was performed to assess the association of melasma with thyroid disorders.Materials and Methods: This case-control study was performed...
متن کاملAscertainment through family history of disease often decreases the power of family-based association studies.
Selection of cases with additional affected relatives has been shown to increase the power of the case-control association design. We investigated whether this strategy can also improve the power of family-based association studies that use the transmission disequilibrium test (TDT), while accounting for the effects of residual polygenic and environmental factors on disease liability. Ascertain...
