Genes affected

SEPTIN12 (HGNC:26348): (septin 12) This gene encodes a guanine-nucleotide binding protein and member of the septin family of cytoskeletal GTPases. Septins play important roles in cytokinesis, exocytosis, embryonic development, and membrane dynamics. Multiple transcript variants encoding different isoforms have been found for this gene.

Dec 28, 2023

The c.1024C>T (p.R342W) alteration is located in exon 10 (coding exon 9) of the SEPT12 gene. This alteration results from a C to T substitution at nucleotide position 1024, causing the arginine (R) at amino acid position 342 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
