"Uncovering the Genetic Basis of Left-Handedness and Neurological Disorders"

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.

"Unraveling the Genetic Basis of Left-Handedness"

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.

"Uncovering the Genetic Links to Left-Handedness: Insights from Rare Variants"

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.

"Uncovering the Genetic Link to Left-Handedness"

A new study has identified rare genetic variants of the TUBB4B gene that are 2.7 times more common in left-handed individuals, shedding light on the genetic component of left-handedness. 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 study also suggests a potential link between genes involved in brain asymmetry and psychiatric traits, such as schizophrenia and autism.

Insights into Child Development from Newborn Brain Studies.

Researchers have found numerous brain asymmetries in newborns' brains, particularly in areas associated with language and visual tasks like facial recognition. The study also found that preterm babies had the same asymmetries as those born to term, suggesting that brain asymmetry may be hard-wired and critical for later brain development. The findings will act as a baseline for future studies investigating how asymmetries relate to brain disorders.
