Genes affected

SH3KBP1 (HGNC:13867): (SH3 domain containing kinase binding protein 1) This gene encodes an adapter protein that contains one or more N-terminal Src homology domains, a proline rich region and a C-terminal coiled-coil domain. The encoded protein facilitates protein-protein interactions and has been implicated in numerous cellular processes including apoptosis, cytoskeletal rearrangement, cell adhesion and in the regulation of clathrin-dependent endocytosis. Alternate splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2017]

This variant has not been reported in the literature in individuals affected with SH3KBP1-related conditions. 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. 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. This variant is present in population databases (no rsID available, gnomAD 0.004%). This sequence change falls in intron 17 of the SH3KBP1 gene. It does not directly change the encoded amino acid sequence of the SH3KBP1 protein. It affects a nucleotide within the consensus splice site. -
