Several models have been developed to predict ASD using genetic information. However, the influence of biological sex on prediction outcomes remains underexplored.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We present an ensemble model to predict ASD, which integrates polygenic risk scores (PRSs), common genetic variants, and ASD risk genes with the MSSNG whole genome sequencing (WGS) dataset.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Following training, our model achieved an accuracy of 0.68, an area under the receiver operating curve (AUROC) of 0.72, and a recall of 0.77 on the test dataset. Notably, common variants contributed more significantly to ASD prediction in males than females (p &amp;lt; 0.001), with accuracies of 0.69 and 0.66, respectively. The 16p11 locus emerged as particularly predictive for females (p &amp;lt; 0.001). Gene enrichment analysis using the Allen Brain Atlas revealed that expression of ASD risk genes that were significant in females were enriched (FWER &amp;lt; 0.05) in the primary somatosensory cortex, inferior parietal cortex, and parietal neocortex during fetal development. By contrast, male ASD risk gene expression was enriched (FWER &amp;lt; 0.05) in the dorsolateral prefrontal cortex and anterior cingulate cortex across developmental stages (fetal to adult).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>These findings underscore a sex-dependent role for common genetic variants in the risk of developing ASD.
