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

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.62).
• BP6: Variant 5-14143721-C-T is Benign according to our data. Variant chr5-14143721-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 3026465.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High AC in GnomAdExome4 at 19 AD gene.
