Genes affected

SEC23IP (HGNC:17018): (SEC23 interacting protein) This gene encodes a member of the phosphatidic acid preferring-phospholipase A1 family. The encoded protein is localized to endoplasmic reticulum exit sites and plays a critical role in ER-Golgi transport as part of the multimeric coat protein II complex. An orthologous gene in frogs is required for normal neural crest cell development, suggesting that this gene may play a role in Waardenburg syndrome neural crest defects. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Feb 2011]

The c.224C>T (p.S75F) alteration is located in exon 2 (coding exon 2) of the SEC23IP gene. This alteration results from a C to T substitution at nucleotide position 224, causing the serine (S) at amino acid position 75 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
