Genes affected

SEPTIN9 (HGNC:7323): (septin 9) This gene is a member of the septin family involved in cytokinesis and cell cycle control. This gene is a candidate for the ovarian tumor suppressor gene. Mutations in this gene cause hereditary neuralgic amyotrophy, also known as neuritis with brachial predilection. A chromosomal translocation involving this gene on chromosome 17 and the MLL gene on chromosome 11 results in acute myelomonocytic leukemia. Multiple alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Mar 2009]

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 271 of the SEPT9 protein (p.Arg271His). This variant is present in population databases (rs587781247, gnomAD 0.003%). This missense change has been observed in individual(s) with Charcot-Marie-Tooth disease (PMID: 25025039). This variant is also known as c.530G>A p.R177H. ClinVar contains an entry for this variant (Variation ID: 157523). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SEPT9 protein function with a negative predictive value of 80%. 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. -
