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 GeneticsNov 18, 2023The c.1028C>A (p.P343H) alteration is located in exon 8 (coding exon 8) of the CD34 gene. This alteration results from a C to A substitution at nucleotide position 1028, causing the proline (P) at amino acid position 343 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
