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]

The c.367G>A (p.V123I) alteration is located in exon 4 (coding exon 4) of the SEPT3 gene. This alteration results from a G to A substitution at nucleotide position 367, causing the valine (V) at amino acid position 123 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
