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.

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]

TRIM32-related condition Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Mar 27, 2023 | The TRIM32 c.196_205del10 variant is predicted to result in a frameshift and premature protein termination (p.Lys66Alafs*2). To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Frameshift variants in TRIM32 are expected to be pathogenic. This variant is interpreted as likely pathogenic. - |
