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 GeneticsAug 05, 2023The c.52A>C (p.T18P) alteration is located in exon 1 (coding exon 1) of the CD34 gene. This alteration results from a A to C substitution at nucleotide position 52, causing the threonine (T) at amino acid position 18 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
