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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.521C>T (p.S174F) alteration is located in exon 2 (coding exon 1) of the TRIM32 gene. This alteration results from a C to T substitution at nucleotide position 521, causing the serine (S) at amino acid position 174 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Review Status:no assertion criteria provided

Collection Method:clinical testing

The TRIM32 c.521C>T variant is predicted to result in the amino acid substitution p.Ser174Phe. This variant has been reported in the heterozygous state in several individuals who presented with unexplained proximal muscle weakness; however, no second variant was identified in these patients and no additional evidence was provided to help determine pathogenicity of the variant (Table S1 - Johnson et al. 2019. PubMed ID: 29921608). This variant is reported in 0.033% of alleles in individuals of European (Non-Finnish) descent in gnomAD. 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 serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 174 of the TRIM32 protein (p.Ser174Phe). This variant is present in population databases (rs138699534, 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: 288658). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). 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. -
