Genes affected
SEPTIN4 (HGNC:9165): (septin 4) 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. This gene is highly expressed in brain and heart. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. One of the isoforms (known as ARTS) is distinct; it is localized to the mitochondria, and has a role in apoptosis and cancer. [provided by RefSeq, Nov 2010]
SEPTIN4-AS1 (HGNC:51345): (SEPTIN4 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 24, 2023The c.1208A>G (p.H403R) alteration is located in exon 10 (coding exon 10) of the SEPT4 gene. This alteration results from a A to G substitution at nucleotide position 1208, causing the histidine (H) at amino acid position 403 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
