Genes affected
SEPTIN8 (HGNC:16511): (septin 8) This gene is a member of the septin family of nucleotide binding proteins, originally described in yeast as cell division cycle regulatory proteins. Septins are highly conserved in yeast, Drosophila, and mouse, and appear to regulate cytoskeletal organization. Disruption of septin function disturbs cytokinesis and results in large multinucleate or polyploid cells. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 13, 2023 | The c.820G>A (p.V274M) alteration is located in exon 7 (coding exon 7) of the SEPT8 gene. This alteration results from a G to A substitution at nucleotide position 820, causing the valine (V) at amino acid position 274 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
