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.

NLGN1 Gene-Disease associations (from GenCC):

• autism, susceptibility to, 20

  Inheritance: Unknown, AD Classification: MODERATE, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.257 is higher than 0.05.
