Genes affected
DLC1 (HGNC:2897): (DLC1 Rho GTPase activating protein) This gene encodes a GTPase-activating protein (GAP) that is a member of the rhoGAP family of proteins which play a role in the regulation of small GTP-binding proteins. GAP family proteins participate in signaling pathways that regulate cell processes involved in cytoskeletal changes. This gene functions as a tumor suppressor gene in a number of common cancers, including prostate, lung, colorectal, and breast cancers. Multiple transcript variants due to alternative promoters and alternative splicing have been found for this gene.[provided by RefSeq, Apr 2010]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 21, 2022In 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. This variant has not been reported in the literature in individuals affected with DLC1-related conditions. This variant is present in population databases (rs761388824, gnomAD 0.006%). This sequence change affects codon 1431 of the DLC1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the DLC1 protein. It affects a nucleotide within the consensus splice site. -
