Genes affected

SEC24B (HGNC:10704): (SEC24 homolog B, COPII coat complex component) The protein encoded by this gene is a member of the SEC24 subfamily of the SEC23/SEC24 family, which is involved in vesicle trafficking. The encoded protein is thought to be a cargo-binding component of the COPII vesicle, and is thought to be involved in the transport of secretory proteins from the endoplasmic reticulum to the Golgi apparatus. Mutations in this gene have been associated with neural tube defects, and are thought to be a result of a disruption in interactions with the protein encoded by the VANGL planar cell polarity protein 2 (VANGL2) gene. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

The c.107C>T (p.A36V) alteration is located in exon 1 (coding exon 1) of the SEC24B gene. This alteration results from a C to T substitution at nucleotide position 107, causing the alanine (A) at amino acid position 36 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
