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.

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]

The c.32T>C (p.L11P) alteration is located in exon 2 (coding exon 1) of the TRIM32 gene. This alteration results from a T to C substitution at nucleotide position 32, causing the leucine (L) at amino acid position 11 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The TRIM32 c.32T>C variant is predicted to result in the amino acid substitution p.Leu11Pro. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.037% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/9-119460053-T-C). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 11 of the TRIM32 protein (p.Leu11Pro). This variant is present in population databases (rs767818381, gnomAD 0.03%). 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: 864083). 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. -
