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 GeneticsAug 02, 2021The c.668A>G (p.Y223C) alteration is located in exon 6 (coding exon 5) of the SEPT14 gene. This alteration results from a A to G substitution at nucleotide position 668, causing the tyrosine (Y) at amino acid position 223 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
