Genes affected

ADGRL1 (HGNC:20973): (adhesion G protein-coupled receptor L1) This gene encodes a member of the latrophilin subfamily of G-protein coupled receptors (GPCR). Latrophilins may function in both cell adhesion and signal transduction. In experiments with non-human species, endogenous proteolytic cleavage within a cysteine-rich GPS (G-protein-coupled-receptor proteolysis site) domain resulted in two subunits (a large extracellular N-terminal cell adhesion subunit and a subunit with substantial similarity to the secretin/calcitonin family of GPCRs) being non-covalently bound at the cell membrane. Latrophilin-1 has been shown to recruit the neurotoxin from black widow spider venom, alpha-latrotoxin, to the synapse plasma membrane. Alternative splicing results in multiple variants encoding distinct isoforms.[provided by RefSeq, Oct 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ADGRL1. . Gene score misZ 3.4265 (greater than the threshold 3.09). Trascript score misZ 4.0179 (greater than threshold 3.09). GenCC has associacion of gene with developmental delay, behavioral abnormalities, and neuropsychiatric disorders.

BP4

Computational evidence support a benign effect (MetaRNN=0.2416783).

BS2

High AC in GnomAdExome4 at 9 AD gene.

The c.4336C>T (p.P1446S) alteration is located in exon 24 (coding exon 23) of the ADGRL1 gene. This alteration results from a C to T substitution at nucleotide position 4336, causing the proline (P) at amino acid position 1446 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
