Genes affected

GOLPH3 (HGNC:15452): (golgi phosphoprotein 3) The Golgi complex plays a key role in the sorting and modification of proteins exported from the endoplasmic reticulum. The protein encoded by this gene is a peripheral membrane protein of the Golgi stack and may have a regulatory role in Golgi trafficking. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of these variants has not been determined. [provided by RefSeq, Jul 2008]

The c.691C>T (p.R231C) alteration is located in exon 4 (coding exon 4) of the GOLPH3 gene. This alteration results from a C to T substitution at nucleotide position 691, causing the arginine (R) at amino acid position 231 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
