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]

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TMPO protein function. ClinVar contains an entry for this variant (Variation ID: 191793). This variant has not been reported in the literature in individuals affected with TMPO-related conditions. This variant is present in population databases (rs373861992, gnomAD 0.008%). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 469 of the TMPO protein (p.Leu469Val). -
