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 submitterclinical testingAmbry GeneticsApr 11, 2023The c.932G>A (p.R311H) alteration is located in exon 10 (coding exon 9) of the SEPT12 gene. This alteration results from a G to A substitution at nucleotide position 932, causing the arginine (R) at amino acid position 311 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
