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.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.295G>C (p.E99Q) alteration is located in exon 3 (coding exon 1) of the NLGN1 gene. This alteration results from a G to C substitution at nucleotide position 295, causing the glutamic acid (E) at amino acid position 99 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
