Genes affected

TRIM32 (HGNC:16380): (tripartite motif containing 32) The protein encoded by this gene is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. The protein localizes to cytoplasmic bodies. The protein has also been localized to the nucleus, where it interacts with the activation domain of the HIV-1 Tat protein. The Tat protein activates transcription of HIV-1 genes. [provided by RefSeq, Jul 2008]

TRIM32 links:

ASTN2 (HGNC:17021): (astrotactin 2) This gene encodes a protein that is expressed in the brain and may function in neuronal migration, based on functional studies of the related astrotactin 1 gene in human and mouse. A deletion at this locus has been associated with schizophrenia. Multiple transcript variants encoding different proteins have been found for this locus. [provided by RefSeq, May 2010]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.034703642).

BP6

Variant 9-116698146-C-T is Benign according to our data. Variant chr9-116698146-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 288372.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000127 (186/1461860) while in subpopulation MID AF = 0.00121 (7/5766). AF 95% confidence interval is 0.000774. There are 2 homozygotes in GnomAdExome4. There are 126 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR gene
