Genes affected
SEPTIN3 (HGNC:10750): (septin 3) This gene belongs to the septin family of GTPases. Members of this family are required for cytokinesis. Expression is upregulated by retinoic acid in a human teratocarcinoma cell line. The specific function of this gene has not been determined. Alternative splicing of this gene results in several transcript variants encoding different isoforms. [provided by RefSeq, May 2018]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 26, 2023 | The c.494G>A (p.R165H) alteration is located in exon 5 (coding exon 5) of the SEPT3 gene. This alteration results from a G to A substitution at nucleotide position 494, causing the arginine (R) at amino acid position 165 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
