Genes affected

NLGN1 (HGNC:14291): (neuroligin 1) 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.

The c.71G>A (p.G24E) alteration is located in exon 3 (coding exon 1) of the NLGN1 gene. This alteration results from a G to A substitution at nucleotide position 71, causing the glycine (G) at amino acid position 24 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
