Mutations and non-coding structural variations at the PITX1 locus have been shown to associate with a variety of congenital limb defects, including clubfeet, polydactyly, and arm-to-leg transformation. As the focus of debate has moved from genetic counselling and eugenics to the promises of therapies and enhancements; genomic research and data sharing; prediction and personalisation; the ethical frameworks have also been tested.

Cuppen: None. Typically genomic regions pinpointed by GWAS contain hundreds of correlated variants and a key step in transforming GWAS information into biological insights is fine-mapping, narrowing down the set of all variants to a much smaller set of most probable causal variants.

If the sperm cell contains a Y chromosome, then the resulting zygote will be XY, or male. Numerous models are used for sex determination in organisms. The Y chromosome has one long arm and a very short second arm. Redirected from Sex chromosomes.

Male chromosome or Y chromosome contains many genes determining various characteristics. After examination, it was discovered that the difference between a typical XX individual traditional female and a sex-reversed XX man was that the typical individuals lacked the SRY gene. In mammals, including humans, the SRY gene is responsible with triggering the development of non-differentiated gonads into testes, rather than ovaries.
