Abstract

In this study, we evaluated the association between autism spectrum disorders (ASDs) and 10 single-nucleotide polymorphisms (SNPs) in the 5' region of the semaphorin 5A gene (SEMA5A) for 250 Korean trios including children with ASDs. Family-based association testing and haplotype analysis revealed a statistically significant association between rs194085 and multiple sociality traits with Korean ASDs in the dominant model (p < 0.001, corrected p=0.035). This indicates that genetic variations in the 5' region of SEMA5A play a role in the genetic predisposition to sociality traits in Korean ASDs.
