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]
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 disorder Uncertain:1
Jul 07, 2023
PreventionGenetics, part of Exact Sciences
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The TRIM32 c.440G>A variant is predicted to result in the amino acid substitution p.Arg147Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0062% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-119460461-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Bardet-Biedl syndrome Uncertain:1
Jul 19, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 147 of the TRIM32 protein (p.Arg147Gln). This variant is present in population databases (rs552938001, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with TRIM32-related conditions. ClinVar contains an entry for this variant (Variation ID: 462948). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
