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 Benign. Variant got -20 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.77).
BP6
Variant 5-14364638-T-A is Benign according to our data. Variant chr5-14364638-T-A is described in ClinVar as [Likely_benign]. Clinvar id is 445482.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0055 (837/152312) while in subpopulation SAS AF= 0.00995 (48/4826). AF 95% confidence interval is 0.00771. There are 8 homozygotes in gnomad4. There are 411 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High AC in GnomAd4 at 837 AD gene.
