Genes affected

CD34 (HGNC:1662): (CD34 molecule) The protein encoded by this gene may play a role in the attachment of stem cells to the bone marrow extracellular matrix or to stromal cells. This single-pass membrane protein is highly glycosylated and phosphorylated by protein kinase C. Two transcript variants encoding different isoforms have been found for this gene.

Jun 06, 2022

The c.654G>C (p.E218D) alteration is located in exon 5 (coding exon 5) of the CD34 gene. This alteration results from a G to C substitution at nucleotide position 654, causing the glutamic acid (E) at amino acid position 218 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
