Dysbiosis in the Family nucleus of Children Diagnosed With Autism Spectrumin Mexico City.

The gut microbiome of children with ASD more closely resembles the mother's microbiome than the father's microbiome.

• Analysis was performed on trio-type families (child with ASD plus both parents) in Mexico City.
• Three families were included in this study.
• Stool samples were collected from adolescents with ASD and their parents.
• The hypervariable region of the 16S ribosomal gene was sequenced from stool samples.
• Analysis was performed using QIIME2 and DADA2 software programs.

Significant differences in gut microbiome abundance and composition exist in ASD children compared to neurotypical children.

• This finding is noted as established in prior scientific research and provides the basis for the current study.
• The paper situates this within the context of growing interest in the relationship between the gut microbiome and ASD.
• The current study extends this prior work by examining microbiome interplay within family units sharing a consistent environment.

Families sharing a consistent environment show microbiome interplay between parents and children with ASD.

• The study design specifically examined trio-type families to investigate shared environmental influences on microbiome composition.
• Little was previously known about microbiome changes and relationships in parents and children with ASD who share a consistent environment.
• Three families in Mexico City were characterized for microbiota composition.

The observed maternal microbiome similarity in ASD offspring suggests potential heritability of the disorder through parental connectedness of the gut microbiome.

• The authors propose this could lead to understanding of 'potential heritability of the disorder through parental connectedness of the gut microbiome.'
• The findings are discussed in the context of eventually developing interventions aimed at modulating the gut microbiota to improve symptoms associated with ASD.
• The study characterizes dysbiosis within the family nucleus rather than in isolated individuals.
