Genes affected

SWI5 (HGNC:31412): (SWI5 homologous recombination repair protein) Involved in cellular response to ionizing radiation and double-strand break repair via homologous recombination. Part of Swi5-Sfr1 complex. [provided by Alliance of Genome Resources, Apr 2022]

SWI5 links:

GOLGA2 (HGNC:4425): (golgin A2) The Golgi apparatus, which participates in glycosylation and transport of proteins and lipids in the secretory pathway, consists of a series of stacked cisternae (flattened membrane sacs). Interactions between the Golgi and microtubules are thought to be important for the reorganization of the Golgi after it fragments during mitosis. This gene encodes one of the golgins, a family of proteins localized to the Golgi. This encoded protein has been postulated to play roles in the stacking of Golgi cisternae and in vesicular transport. 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, Feb 2010]

The c.76C>G (p.R26G) alteration is located in exon 1 (coding exon 1) of the SWI5 gene. This alteration results from a C to G substitution at nucleotide position 76, causing the arginine (R) at amino acid position 26 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
