Résumé

The number of words children produce (expressive vocabulary) and understand (receptive vocabulary) changes rapidly during early development, partially due to genetic factors. Here, we performed a meta-genome-wide association study of vocabulary acquisition and investigated polygenic overlap with literacy, cognition, developmental phenotypes and neurodevelopmental conditions, including Attention-Deficit/Hyperactivity Disorder (ADHD). We studied 37,913 parent-reported vocabulary size measures (English, Dutch, Danish) for 17,298 European descent children. Meta-analyses were performed for early-phase expressive (infancy, 15-18 months), late-phase expressive (toddlerhood, 24-38 months) and late-phase receptive (toddlerhood, 24-38 months) vocabulary. Subsequently, we estimated Single-Nucleotide Polymorphism heritability (SNP-h Early-life vocabulary size was modestly heritable (SNP-h The genetic architecture of early-life vocabulary changes during development, shaping polygenic association patterns with later-life ADHD, literacy and cognition-related traits.

BACKGROUND BACKGROUND
The number of words children produce (expressive vocabulary) and understand (receptive vocabulary) changes rapidly during early development, partially due to genetic factors. Here, we performed a meta-genome-wide association study of vocabulary acquisition and investigated polygenic overlap with literacy, cognition, developmental phenotypes and neurodevelopmental conditions, including Attention-Deficit/Hyperactivity Disorder (ADHD).
METHODS METHODS
We studied 37,913 parent-reported vocabulary size measures (English, Dutch, Danish) for 17,298 European descent children. Meta-analyses were performed for early-phase expressive (infancy, 15-18 months), late-phase expressive (toddlerhood, 24-38 months) and late-phase receptive (toddlerhood, 24-38 months) vocabulary. Subsequently, we estimated Single-Nucleotide Polymorphism heritability (SNP-h
RESULTS RESULTS
Early-life vocabulary size was modestly heritable (SNP-h
CONCLUSIONS CONCLUSIONS
The genetic architecture of early-life vocabulary changes during development, shaping polygenic association patterns with later-life ADHD, literacy and cognition-related traits.
