A comprehensive review of over a century of research shows that left-handed people are not inherently more creative than right-handed people, and in fact, are underrepresented in highly creative professions, debunking the myth that lefties are more creative.

A study using UK Biobank data has identified rare variants in the TUBB4B gene significantly associated with left-handedness, shedding light on the genetic basis of this trait and its link to neurodevelopmental disorders. Despite the influence of these rare genetic variants, they account for less than 1% of the heritability of left-handedness, indicating a complex interplay of factors in determining this trait. The findings offer insights into the genetic intricacies of left-handedness and its connection to brain asymmetry and neurodevelopmental disorders, providing new avenues for investigating the developmental pathways leading to brain asymmetry.

A new study sheds light on a genetic component of left-handedness, identifying rare variants of the TUBB4B gene that are 2.7 times more common in left-handed people. These variants may play a role in the development of brain asymmetry that determines dominant hand. The findings, based on genetic data from over 350,000 adults, suggest that microtubules controlled by TUBB4B are involved in setting up the brain's normal asymmetries. The prevalence of left-handedness varies globally, possibly reflecting cultural suppression. The study's findings may have relevance in psychiatry, as genes involved in brain asymmetry may also be linked to psychiatric traits.

Researchers at the Max Planck Institute have identified rare protein-altering genetic variants associated with left-handedness, shedding light on the inheritable nature of this trait. Using data from the UK Biobank, they found that microtubule-related genes, such as TUBB4B, may play a role in setting up brain asymmetries. Additionally, genes associated with autism, DSCAM and FOXP1, were linked to left-handedness, providing potential insights into conditions like autism and schizophrenia. The study highlights the complexity of handedness as a polygenic trait and paves the way for further exploration of brain asymmetry in embryonic development.

A study has linked rare genetic variants to left-handedness, finding that people with these variants are more likely to be left-handed. The study also suggests potential connections between left-handedness and neurodevelopmental disorders, as well as genes associated with autism. Researchers identified a gene called TUBB4B, which codes for microtubules important for neuron development, as being linked to left-handedness. The findings provide further evidence for the involvement of specific genes in determining left-handedness and may lead to a better understanding of how genes contribute to brain development and disorders.

A new study sheds light on a genetic component of left-handedness, identifying rare variants of the TUBB4B gene that are 2.7 times more common in left-handed people, suggesting a role in brain asymmetry development. The gene controls a protein integrated into cells' microtubules, providing insight into the brain's normal asymmetries. The findings, based on genetic data from over 350,000 adults, may have relevance in psychiatry, as left-handedness is associated with conditions like schizophrenia and autism.
