Genes affected
TRIOBP (HGNC:17009): (TRIO and F-actin binding protein) This gene encodes a protein with an N-terminal pleckstrin homology domain and a C-terminal coiled-coil region. The protein interacts with trio, which is involved with neural tissue development and controlling actin cytoskeleton organization, cell motility and cell growth. The protein also associates with F-actin and stabilizes F-actin structures. Mutations in this gene have been associated with a form of autosomal recessive nonsyndromic deafness. Multiple alternatively spliced transcript variants that would encode different isoforms have been found for this gene, however some transcripts may be subject to nonsense-mediated decay (NMD).

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.007600248).
BP6
Variant 22-37765707-C-T is Benign according to our data. Variant chr22-37765707-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 165609.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000552 (84/152210) while in subpopulation SAS AF = 0.0056 (27/4822). AF 95% confidence interval is 0.00395. There are 1 homozygotes in GnomAd4. There are 49 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 7 AR gene
