The ratio of 2nd to 4th digit length: a new predictor of disease predisposition?J T Manning
School of Biological Sciences, University of Liverpool, Liverpool, UK
Med Hypotheses 54:855-7. 2000..We suggest that 2D:4D ratio is predictive of these diseases and may be used in diagnosis, prognosis and in early life-style interventions which may delay the onset of disease or facilitate its early detection...- The ratio of 2nd to 4th digit length and performance in skiingJ T Manning

J Sports Med Phys Fitness 42:446-50. 2002..There is evidence that low 2D:4D ratio is associated with high prenatal and adult levels of testosterone, good visuo-spatial ability, protection against heart attack, high self-reported sporting attainment and good soccer ability... - Second to fourth digit ratio: ethnic differences and family size in English, Indian and South African populationsJ T Manning

School of Biological Sciences, University of Liverpool, Liverpool, UK
Med Hypotheses 59:334-6. 2002..Findings from 2D:4D studies predict that short CAG length will be common in autism and Asperger's syndrome, while high numbers of CAG repeats will be found in men who are prone to early myocardial infarction... - Finger and toe ratios in humans and mice: implications for the aetiology of diseases influenced by HOX genesJ T Manning

Population and Evolutionary Biology Research Group, School of Biological Sciences, University of Liverpool, United Kingdom
Dev Med Child Neurol 43:160-4. 2001..It was concluded that 2D:4D ratio may be a possible marker for autism which could implicate prenatal testosterone in its aetiology... - 2nd to 4th digit ratio and a universal mean for prenatal testosterone in homosexual menJ T Manning
School of Biological Sciences, University of Liverpool, UK
Med Hypotheses 61:303-6. 2003..Speculations regarding the effect of early sex steroids on the health of male homosexuals should therefore focus on the effects of prenatal testosterone levels associated with 2D:4D ratios of between 0.96 and 0.97... - 2nd to 4th digit ratio and offspring sex ratioJ T Manning
Population Biology Research Group, School of Biological Sciences, University of Liverpool, Liverpool, UK
J Theor Biol 217:93-5. 2002..We present evidence from three populations (English, Spanish and Jamaican) that 2D:4D is negatively related to sex ratio, independent of the sex and ethnicity of the parents... - Maternal smoking during pregnancy and possible effects of in utero testosterone: evidence from the 2D:4D finger length ratioS Rizwan

Developmental Psychiatry Section, University of Cambridge, Douglas House, 18b Trumpington Road, Cambridge CB2 2AH, UK
Early Hum Dev 77:23-8. 2004..CONCLUSIONS: These preliminary findings lend support to an association between low 2D:4D and high levels of FT relative to FE, and high 2D:4D with low FT relative to FE... - Sex and ethnic differences in 2nd to 4th digit ratio of childrenJ T Manning
Department of Psychology, The University of Central Lancashire, Preston PR1 2HE, UK

Department of Child Health, The Medical School, University of Aberdeen, Foresterhill, Aberdeen, AB25 2ZD, UK
Early Hum Dev 72:57-65. 2003..Behaviours such as hyperactivity and poor social cognition are common in preschoolers. An association between 2D:4D and these possible precursors of psychopathology would be most readily identified in this group... - "Constitutive" skin pigmentation: a marker of breast cancer risk?J T Manning
Department of Psychology, University of Central Lancashire, Preston PR1 2HE, UK
Med Hypotheses 63:787-9. 2004..Scores for 'constitutive' skin pigment may therefore be predictive of risk for breast cancer and low scores could be used to identify individuals at high risk... - Second to fourth digit ratio (2D:4D) and testosterone in menJ T Manning
