Summaries for NLGN4X Gene

Entrez Gene Summary for NLGN4X Gene

  • This gene encodes a member of the type-B carboxylesterase/lipase protein family. The encoded protein belongs to a family of neuronal cell surface proteins. Members of this family may act as splice site-specific ligands for beta-neurexins and may be involved in the formation and remodeling of central nervous system synapses. The encoded protein interacts with discs large homolog 4 (DLG4). Mutations in this gene have been associated with autism and Asperger syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

GeneCards Summary for NLGN4X Gene

NLGN4X (Neuroligin 4, X-Linked) is a Protein Coding gene. Diseases associated with NLGN4X include autism susceptibility, x-linked 2 and nlgn4-related x-linked mental retardation. Among its related pathways are Cell adhesion molecules (CAMs). GO annotations related to this gene include protein homodimerization activity and neurexin family protein binding. An important paralog of this gene is CES2.

Disorders for NLGN4X Gene

(2) OMIM Diseases for NLGN4X Gene (300427)


  • Autism, X-linked 2 (AUTSX2) [MIM:300495]: A complex multifactorial, pervasive developmental disorder characterized by impairments in reciprocal social interaction and communication, restricted and stereotyped patterns of interests and activities, and the presence of developmental abnormalities by 3 years of age. Most individuals with autism also manifest moderate mental retardation. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
  • Asperger syndrome, X-linked, 2 (ASPGX2) [MIM:300497]: A syndrome with features similar to autism. Affected individuals exhibit qualitative impairment in social interaction, as manifest by impairment in the use of non-verbal behaviors such as eye-to-eye gaze, facial expression, body postures, and gestures, failure to develop appropriate peer relationships, and lack of social sharing or reciprocity. Patients also exhibit restricted, repetitive and stereotyped patterns of behavior, interests, and activities, including abnormal preoccupation with certain activities and inflexible adherence to routines or rituals. Asperger syndrome is primarily distinguished from autism by the higher cognitive abilities and a more normal and timely development of language and communicative phrases. {ECO:0000269 PubMed:14963808}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
