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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2023The c.206G>A (p.S69N) alteration is located in exon 2 (coding exon 2) of the CD34 gene. This alteration results from a G to A substitution at nucleotide position 206, causing the serine (S) at amino acid position 69 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
