Genes affected

SEPTIN14 (HGNC:33280): (septin 14) SEPT14 is a member of the highly conserved septin family of GTP-binding cytoskeletal proteins implicated in membrane transport, apoptosis, cell polarity, cell cycle regulation, cytokinesis, and other cellular functions (Peterson et al., 2007 [PubMed 17922164]).[supplied by OMIM, Jul 2008]

Jul 21, 2021

The c.1269T>A (p.D423E) alteration is located in exon 10 (coding exon 9) of the SEPT14 gene. This alteration results from a T to A substitution at nucleotide position 1269, causing the aspartic acid (D) at amino acid position 423 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
