Genes affected

GOLGA6B (HGNC:32205): (golgin A6 family member B) This gene is found in a large, low copy repeat sequence or duplicon that is found in multiple copies, which are greater than 90% similar, on chromosome 15. Duplicons are associated with deletions, inversions and other chromosomal rearrangements that underlie genomic disease. This gene is a member of the golgin gene family, whose protein products localize to the Golgi apparatus. The majority of the related gene copies are thought to be transcribed pseudogenes. It is not known whether this gene is a pseudogene or if it encodes a golgin protein. [provided by RefSeq, Jul 2008]

The c.1102C>T (p.R368W) alteration is located in exon 11 (coding exon 11) of the GOLGA6B gene. This alteration results from a C to T substitution at nucleotide position 1102, causing the arginine (R) at amino acid position 368 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
