Low second to fourth digit ratio in Dupuytren disease
The ratio of the lengths of the second and fourth digits (2D:4D) has been described as reflecting endogenous prenatal androgen exposure. In general, 2D:4D is lower in men than in women and has potential as a biomarker or predictor for various diseases, athletic ability, and academic performance. Dupuytren disease has digital flexion contractures and is known to predominate in men, but the patho...
متن کاملThe Ratio of Second to Fourth Digit Length (2D:4D) in Children with Autistic Disorder
Introduction Emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of Autism spectrum disorders (ASD). The ratios of the lengths of the bones of the 2nd to the 4th digits (2D:4D) are purported to be markers for prenatal androgen exposure and to be established early in gestation. Ratio of second and fourth digits (2D:4D) is usually used as a proxy for prenatal t...
متن کاملAssociation between Second to Fourth Digit Ratio with Handwriting Quality and Speed among Elementary School Children
Background Genetic impacts on handwriting legibility and speed, especially in early childhood, are not well understood. The present study used a 2D:4D ratio as a biological marker to investigate the associations between genetic factors with quality and speed of handwriting among the elementary school children. Ma...
متن کاملSecond to fourth digit ratio and numerical competence in children.
The ratio between the 2nd and 4th fingers (2D:4D)-a potential proxy for prenatal testosterone (T) exposure-shows a sex difference, with males usually having lower mean values; the latter potentially indicates higher prenatal T exposure. We studied relations between 2D:4D and competencies in the domains of counting, number knowledge, and visual-number representation in 73 children aged 6-11 year...
متن کاملM.b. Wieling - Second-to-fourth Digit Ratio Related to Jealousy
The ratio of index finger length to ring finger length (2D:4D) is an index of prenatal androgen exposure. The larger the exposure to androgens, the smaller this ratio will be. Androgens “masculinise” people and may influence individual differences in a predictable way. In a study with 109 participants, 46 men and 63 women, the relationship between 2D:4D and jealousy was assessed. In a jealousy ...
