Genes affected

MATCAP2 (HGNC:22206): (microtubule associated tyrosine carboxypeptidase 2)

MATCAP2 links:

ANLN (HGNC:14082): (anillin, actin binding protein) This gene encodes an actin-binding protein that plays a role in cell growth and migration, and in cytokinesis. The encoded protein is thought to regulate actin cytoskeletal dynamics in podocytes, components of the glomerulus. Mutations in this gene are associated with focal segmental glomerulosclerosis 8. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]

This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with ANLN-related conditions. Nucleotide substitutions within 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 is not likely to affect RNA splicing, but this prediction has not been confirmed by published transcriptional studies. 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. This sequence change falls in intron 1 of the ANLN gene. It does not directly change the encoded amino acid sequence of the ANLN protein. It affects a nucleotide within the consensus splice site of the intron. -
