Abstract
Cancers are genetically categorized into common diseases showing a so-called multifactorial inheritance except for rare familial cancers. And as a measure to estimate the strength of genetic factors in the multifactorial diseases, heritability (h2) is generally used. However, there have been few reports on the estimation of heritability for cancers. We calculated the heritability from the incidence in subject population and the familial recurrence rate in first-degree relatives of the affected for cancers quoting the data from a large-scale prospective cohort study by Hidaka et al. published in 2020. This is the first report for heritability of any cancers in Japanese population. The results showed that heritability of overall cancers in Japanese population is 0.064, which is much lower than Nordic population reported by Mucci et al. that was 0.33. For individual cancers, stomach cancer (h2 = 0.14), colorectum cancer (0.006), lung cancer (0.08) and uterine cancer (0.16) accounted for half of the total patients, and each heritability tends to be lower than previously reported for the European descent. The results of this study suggest that heritability of cancers varies greatly by ethnicity. And these results should be important in terms of cancer genetics and in the genetic counseling for cancers.
期刊介绍:
Clinical Genetics links research to the clinic, translating advances in our understanding of the molecular basis of genetic disease for the practising clinical geneticist. The journal publishes high quality research papers, short reports, reviews and mini-reviews that connect medical genetics research with clinical practice.
Topics of particular interest are:
• Linking genetic variations to disease
• Genome rearrangements and disease
• Epigenetics and disease
• The translation of genotype to phenotype
• Genetics of complex disease
• Management/intervention of genetic diseases
• Novel therapies for genetic diseases
• Developmental biology, as it relates to clinical genetics
• Social science research on the psychological and behavioural aspects of living with or being at risk of genetic disease
