Genes affected

NLGN3 (HGNC:14289): (neuroligin 3) This gene encodes a member of 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. Mutations in this gene may be associated with autism and Asperger syndrome. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Oct 2009]

Jul 14, 2021

The c.241G>A (p.E81K) alteration is located in exon 2 (coding exon 1) of the NLGN3 gene. This alteration results from a G to A substitution at nucleotide position 241, causing the glutamic acid (E) at amino acid position 81 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
