Genes affected
TPR (HGNC:12017): (translocated promoter region, nuclear basket protein) This gene encodes a large coiled-coil protein that forms intranuclear filaments attached to the inner surface of nuclear pore complexes (NPCs). The protein directly interacts with several components of the NPC. It is required for the nuclear export of mRNAs and some proteins. Oncogenic fusions of the 5' end of this gene with several different kinase genes occur in some neoplasias. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TPR. . Gene score misZ 2.9916 (greater than the threshold 3.09). Trascript score misZ 3.9792 (greater than threshold 3.09). GenCC has associacion of gene with intellectual developmental disorder, autosomal recessive 79.
BP4
Computational evidence support a benign effect (MetaRNN=0.050374538).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2023The c.6760A>G (p.T2254A) alteration is located in exon 48 (coding exon 48) of the TPR gene. This alteration results from a A to G substitution at nucleotide position 6760, causing the threonine (T) at amino acid position 2254 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
