Genes affected
TMPO (HGNC:11875): (thymopoietin) Through alternative splicing, this gene encodes several distinct LEM domain containing protein isoforms. LEM domain proteins include inner nuclear membrane and intranuclear proteins, and are involved in a variety of cellular functions including gene expression, chromatin organization, and replication and cell cycle control. The encoded alpha isoform is broadly diffuse in the nucleus and contains a lamin binding domain, while the beta and gamma isoforms are localized to the nuclear membrane and contain an HDAC3 interaction domain. The distinct isoforms may compete with each other when acting to chaperone other proteins and regulate transcription. [provided by RefSeq, Aug 2019]

not specified Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJan 29, 2015Variant classified as Uncertain Significance - Favor Benign. The p.Ala577Val var iant in TMPO has not been previously reported in individuals with cardiomyopathy , but has been identified in 0.2% (24/10554) of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs34150443) . Computational prediction tools and conservation analysis suggest that this var iant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, while the clinical significance of the p.A la577Val variant is uncertain, its frequency suggests that it is more likely to be benign. -
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2017The p.A577V variant (also known as c.1730C>T), located in coding exon 4 of the TMPO gene, results from a C to T substitution at nucleotide position 1730. The alanine at codon 577 is replaced by valine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
