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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 03, 2024 | The c.788T>A (p.V263D) alteration is located in exon 8 (coding exon 7) of the SEPT12 gene. This alteration results from a T to A substitution at nucleotide position 788, causing the valine (V) at amino acid position 263 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
