Special Issue Information
Dear Colleagues,
Autism spectrum disorder (ASD) is a neurodevelopmental disorder (NDD) affecting approximately 1 in 59 individuals worldwide, indexed by an estimated heritability of 64–91%. Although autism is characterized by difficulty in social interactions and a tendency toward repetitive and/or stereotyped behaviors, ASD is highly heterogeneous with different degrees of severity. Nowadays, there is no unifying theory that can explain the syndrome according to a linear cause-effect model. Genetic variation include single gene disorders, copy number variants (CNVs), inherited and de novo rare variants, and common sequence variants, whose differences lead to genetic heterogeneity. In the literature, more than 1000 genes have been associated with it: some of these genes are involved in the development and regulation of neural circuits, i.e., neuronal connectivity and synaptic plasticity, however, they do not fully explain the complexity of ASD. This points out the necessity to investigate the role played by additional gene families and their related pathways in ASD. Identifying new genes will allow to better understand the complexity of ASD, and characterize different phenotypes to achieve an early diagnosis and management for the benefit of patients and their families.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
