Genes affected
TRIP11 (HGNC:12305): (thyroid hormone receptor interactor 11) This gene was identified based on the interaction of its protein product with thyroid hormone receptor beta. This protein is associated with the Golgi apparatus. The N-terminal region of the protein binds Golgi membranes and the C-terminal region binds the minus ends of microtubules; thus, the protein is thought to play a role in assembly and maintenance of the Golgi ribbon structure around the centrosome. Mutations in this gene cause achondrogenesis type IA.[provided by RefSeq, Mar 2010]

Variant summary: TRIP11 c.5719+2T>C is located in a canonical splice-site and is predicted to affect mRNA splicing resulting in a significantly altered protein due to either exon skipping, shortening, or inclusion of intronic material. Several computational tools predict a significant impact on normal splicing: Three predict the variant abolishes a canonical 5' splicing donor site. However, these predictions have yet to be confirmed by functional studies. To our knowledge c.5719+2T>C has not been reported in the literature in individuals affected with TRIP11-Related Disorders and no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 30609409, 33578785). Four submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Variant classified as Uncertain Significance - Favor Pathogenic. The c.5719+2T>C variant in TRIP11 has not been reported in individuals with Achondrogenesis typ e 1A but has been identified in 0.016% (20/127174) of European chromosomes by gn omAD (http://gnomad.broadinstitute.org). This variant occurs within the canonica l splice site (+/- 1,2) and is predicted to cause altered splicing leading to an abnormal or absent protein; however, this splice variant disrupts the donor spl ice site of the penultimate exon and therefore may escape nonsense mediated deca y. Additionally, no loss of function variants downstream of this variant have be en reported in individuals with disease. In summary, while there is some suspici on for a pathogenic role, the clinical significance of the c.5719+2T>C variant i s uncertain. ACMG/AMP Criteria applied: PVS1_Moderate. -

This sequence change affects a donor splice site in intron 20 of the TRIP11 gene. While this variant is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product. This variant is present in population databases (rs199736345, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with TRIP11-related conditions. ClinVar contains an entry for this variant (Variation ID: 505515). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
