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]

The c.796T>C (p.Y266H) alteration is located in exon 7 (coding exon 6) of the SEPT14 gene. This alteration results from a T to C substitution at nucleotide position 796, causing the tyrosine (Y) at amino acid position 266 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
