Genes affected
SEC24A (HGNC:10703): (SEC24 homolog A, COPII coat complex component) The protein encoded by this gene belongs to a family of proteins that are homologous to yeast Sec24. This protein is a component of coat protein II (COPII)-coated vesicles that mediate protein transport from the endoplasmic reticulum. COPII acts in the cytoplasm to promote the transport of secretory, plasma membrane, and vacuolar proteins from the endoplasmic reticulum to the golgi complex. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2021The c.1077G>A (p.M359I) alteration is located in exon 6 (coding exon 6) of the SEC24A gene. This alteration results from a G to A substitution at nucleotide position 1077, causing the methionine (M) at amino acid position 359 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
