Genes affected
TRIO (HGNC:12303): (trio Rho guanine nucleotide exchange factor) This gene encodes a large protein that functions as a GDP to GTP exchange factor. This protein promotes the reorganization of the actin cytoskeleton, thereby playing a role in cell migration and growth. Alternative splicing results in multiple transcript variants.

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), TRIO. . Gene score misZ 5.3161 (greater than the threshold 3.09). Trascript score misZ 4.6722 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 40, syndromic intellectual disability, intellectual developmental disorder, autosomal dominant 63, with macrocephaly, micrognathia-recurrent infections-behavioral abnormalities-mild intellectual disability syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.16338447).
BS2
High AC in GnomAdExome4 at 32 AD gene.
