Genes affected

NLGN4X (HGNC:14287): (neuroligin 4 X-linked) 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]

The c.2390C>A (p.T797N) alteration is located in exon 6 (coding exon 5) of the NLGN4X gene. This alteration results from a C to A substitution at nucleotide position 2390, causing the threonine (T) at amino acid position 797 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
