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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.1040G>A (p.R347K) alteration is located in exon 9 (coding exon 8) of the SEPT14 gene. This alteration results from a G to A substitution at nucleotide position 1040, causing the arginine (R) at amino acid position 347 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
