(A) Family pedigrees of the two probands (Case 1 and Case 2) identified in this study and presenting GD and ASD features. Sequence chromatograms of nucleotides 70367955-70367975 and nucleotides 70367752-70367772 of the NLGN3 coding sequence in Case 1, Case 2 and their unaffected mothers (the positions of the C>T and G>A are highlighted by the red boxes). (B) Schematic representation of NLGN3 protein (encoded by the NM_181303.1 transcript): signal peptide (light blue), extracellular (green), transmembrane (yellow) and intracellular (orange) domains. All missense variants (gray dots) reported in gnomAD database (v2.1.1) are plotted according to their amino acid (aa) position and Combined Annotation-Dependent Depletion (CADD) score. Pathogenic variants related to ASD are indicated in black: R471C (Jamain et al., 2003), P534S (Quartier et al., 2019) and R617W (Redin et al., 2014). Identified variants (R55* and W122*) are indicated in red and have a higher CADD score compared to others. Multi-species alignment of partial protein sequences of vertebrate NLGN3 ortholog proteins shows that the R55 and W122 residues are evolutionarily conserved in humans and other vertebrate species with a high conservation degree, calculated by GERP++.

    a. Workflow depicting treatment of glioma cells or OPCs for 1 hour with recombinant NLGN3 ectodomains (to mimic naturally shed NLGN3) followed by conditioned medium (CM) concentration and western blot to detect shedding of CSPG4. b. Left : CSPG4 Western blot from diffuse intrinsic pontine glioma model SU-DIPG13 conditioned medium after exposure to 100 nM sNLGN3 for 1-hour in the presence or absence of 5 uM ADAM10 inhibitor. CSPG4 exists as a ‘part-time’ proteoglycan and is detected as either a core protein (discrete band at ∼268 kDa) or as a chondroitin sulfate proteoglycan (higher molecular weight smear). Treatment of conditioned medium with chondroitinase ABC removes chondroitin sulfate chains and collapses diffuse smears into discrete bands. A c-terminal specific CSPG4 antibody only detects protein in the cell lysate control lane, confirming that conditioned medium bands are shed ectodomains. NLGN3 treatment increases shedding relative to vehicle controls (p = 0.003). NLGN3-induced shedding of CSPG4 is blocked by pre-treating cells with 5 uM ADAM10 inhibitor (p = <0.0001). Right : Quantification of CSPG4 shedding as fold change in protein band intensities in the left (top N-terminal blot) relative to vehicle-treated controls. n (independent biological replicates of western blot) = 4, mean ± s.e.m., ordinary one-way ANOVA, p-values are mentioned in the legend and written on the figures. c. Left : Western blot of CSPG4 shedding from IDH1 WT glioblastoma (GBM) model conditioned medium after exposure to 100 nM sNLGN3 for 1-hour in the presence or absence of 5 uM ADAM10 inhibitor. NLGN3 treatment increases shedding relative to vehicle controls (p = 0.0013). NLGN3-induced shedding of CSPG4 is blocked by pre-treating cells with 5 uM ADAM10 inhibitor (p = <0.0001).

NLGN3 treatment increases shedding relative to vehicle controls (p = 0.0066). NLGN3-induced shedding of CSPG4 is blocked by pre-treating cells with 5 uM ADAM10 inhibitor (p = 0.0004). Right : Quantification of protein band intensities relative to vehicle-treated controls. n (independent biological replicates of western blot) = 4, mean ± s.e.m., ordinary one-way ANOVA, p-values are mentioned in the text and the figures. e.

NLGN3 treatment increases shedding relative to vehicle controls (p = 0.0011). NLGN3-induced shedding of CSPG4 is blocked by pre-treating cells with 5 uM ADAM10 inhibitor (p = 0.0003) Right : Quantification of protein band intensities relative to vehicle-treated controls. n (independent biological replicates of western blot) = 3, mean ± s.e.m., ordinary one-way ANOVA, p-values are mentioned in the figures. f.

White dashed line boxes indicate areas shown at higher magnification on the right of the corresponding panel, with single channels also shown adjacent to the panel. Open arrowheads indicate examples of GnRH-positive cells that lack NLGN3; filled arrowheads indicate examples of GnRH-positive cells with NLGN3. Arrows indicate examples of NLGN3- positive cells in the nasal parenchyma. Sections were counterstained with DAPI. MPOA, medial preoptic area; OB, olfactory bulb; OE, olfactory epithelium; VNO, vomeronasal organ. Scale bars: 250 μm (right panels), 150 μm (middle panels) or 50 μm (left panels).

    Fig. 5. Mutant NLGN3 proteins induce endoplasmic reticulum retention and impair neuritogenesis in immortalized GnRH neurons. (A) Immunoblot analysis with anti-HA or anti-GAPDH antibodies on whole-cell lysates and conditioned media from COS7 cells overexpressing control vector (GFP), HA- tagged wild-type (WT) or mutant NLGN3. GAPDH is shown as a loading control for cell lysates. (B) Confocal images of GN11 cells transfected cells with mEmerald-ER-3 (green) and human WT or mutated HA-tagged NLGN3 vectors and stained for HA (red) after 24 h. HA-NLGN3 single-channel images are shown below each panel. (C) Confocal images of GN11 transfected with human WT or mutated NLGN3 HA-tagged encoding vector and stained for HA (green) and F-actin (red). Arrowheads point at neurites in NLGN3 WT-expressing GN11 cells. (D) Quantification of cell perimeter (P), cell area (A), aspect ratio (AR) and complexity index (CI) in GN11 cells transfected with indicated plasmids. Column graph quantifications show a significant increase in the number of neurites extending from NLGN3 WT-expressing cells compared to NLGN3 mutants and GFP-transfected control cells. Data are presented as mean±s.d. of three biological replicates. Significant differences were determined by one-way ANOVA followed by Tukey’s multiple comparison test (***P<0.001; ****P<0.0001). Nuclei were counterstained with DAPI. Scale bars: 25 μm.

    A - Family pedigrees of the two probands (case 1 and case 2) identified in this study and presenting GD and ASD features. Sequence chromatograms of nucleotides 70367955-70367975 of the NLGN3 coding sequence in proband 1 and his unaffected parent (the position of the G>A is highlighted by the red box). B - Schematic representation of NLGN3 protein (encoded by the NM_181303.1 transcript): signal peptide (sp, light blue), extracellular (green), transmembrane (tm, yellow) and intracellular (red) domains. All missense variants (grey dots) reported in gnomAD database (v2.1.1) are plotted according to their aminoacidic position and CADD score. Pathogenic variants related to ASD are indicated in black: R471C , P534S and R617W . Identified variants (R55* and W122*) are indicated in red and have a higher CADD score compared to others. Multi-species alignment of partial protein sequences of vertebrate NLGN3 orthologue proteins shows that the R55 and W122 residues are evolutionarily conserved in humans and other vertebrate species with a high conservation degree, calculated by GERP++.
