Family history, diabetes, and other demographic and risk factors among participants of the National Health and Nutrition Examination Survey 1999-2002.

Introduction: Family history of diabetes has been recognized as an important risk factor of the disease. Family medical history represents valuable genomic information because it characterizes the combined interactions between environmental, behavioral, and genetic factors. This study examined the strength and effect of having a family history of diabetes on the prevalence of self-reported, previously diagnosed diabetes among adult participants of the National Health and Nutrition Examination Survey 199-2002.

Mutation of the FOXC2 gene in familial distichiasis.

Objective: To examine the FOXC2 gene in a family with hereditary distichiasis.

Background: Distichiasis, ie, a second row of eyelashes arising from the meibomian glands of the eyelids, can be inherited either alone (Online Mendelian Inheritance in Man [OMIM] no. 126300) or, more commonly, as part of the lymphedema-distichiasis (LD) syndrome (OMIM no.

FOXC2 haploinsufficient mice are a model for human autosomal dominant lymphedema-distichiasis syndrome.

Lymphedema-distichiasis (LD) (OMIM 153400) is a rare autosomal-dominant condition characterized by pubertal onset of lower limb lymphedema and an aberrant second row of eyelashes arising from the meibomian glands. In some patients cardiac, skeletal and other defects coexist. We previously identified inactivating, nonsense and frameshift mutations in the forkhead transcription factor FOXC2 in affected members of LD families.
