Genes affected

CCDC28A (HGNC:21098): (coiled-coil domain containing 28A) This gene encodes a coiled-coil domain containing protein. Although the specific function of this gene has not yet been determined, this gene is a known translocation partner of nucleoporin 98 in acute leukemias. The resulting fusion gene produces a nucleoporin 98-coiled-coil domain-containing protein 28A chimeric protein which may be involved in promoting myeloproliferative neoplasms.

The c.133G>A (p.V45M) alteration is located in exon 1 (coding exon 1) of the CCDC28A gene. This alteration results from a G to A substitution at nucleotide position 133, causing the valine (V) at amino acid position 45 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
