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.

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NLGN1. . Gene score misZ 2.2182 (greater than the threshold 3.09). Trascript score misZ 3.3825 (greater than threshold 3.09). GenCC has associacion of gene with autism, susceptibility to, 20.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.803
