Another group of genes affected by pathogenic variants includes those related to intellectual disability, such as MED13L and MED13, as well as others associated with certain syndromic conditions, such as CREBBP and SETD2. Consequently, we can establish the following candidate genes, which have been less frequently described concerning ASD: MED13L, SCN2A, CACNA1A, MED13, and EEF1A2. This evidence concerns the gene SCN2A and Intellectual disability.
