Anxiety

Human personality is shaped by genetic and environmental factors, and evidence suggests that the genetic component is highly complex, polygenic, and epistatic. Genetic factors are thought to contribute to 40 to 60% of trait variance. Molecular genetics has tried to identify specific genes for quantitative traits, called quantitative trait loci (QTLs). The QTL concept suggests that complex personality traits or dimensions are not attributable to single genes, but to multiple interacting genes (Reif and Lesch, 2003). Fullerton et al. (2003) stated that psychologists were in agreement that the wide variation in human personalities can be explained by a small number of personality factors, including neuroticism (a measure of emotional stability), which manifests at one extreme as anxiety, depression, moodiness, low self-esteem, and diffidence. They cited a number of studies that had described a relationship between high scores on measures of neuroticism and major depressive disorder. They also noted that theoretical studies had suggested that large samples of randomly ascertained sibs could be used to ascertain phenotypically extreme individuals and thereby increase power to detect genetic linkage in complex traits. See also panic disorder (PAND1; 167870), which is a subtype of anxiety disorder. [from GTR]

Short stature, optic nerve atrophy, and Pelger-Huet anomaly

Among the Yakuts, an Asian population isolate that is located in the northeastern part of Siberia, Maksimova et al. (2010) ascertained a short stature syndrome involving autosomal recessive postnatal growth failure, small hands and feet, loss of visual acuity with abnormalities of color vision, abnormal nuclear shape in neutrophil granulocytes (Pelger-Huet anomaly; see 169400), and normal intelligence. [from GTR]
