Genes affected

CLEC11A (HGNC:10576): (C-type lectin domain containing 11A) This gene encodes a member of the C-type lectin superfamily. The encoded protein is a secreted sulfated glycoprotein and functions as a growth factor for primitive hematopoietic progenitor cells. An alternative splice variant has been described but its biological nature has not been determined. [provided by RefSeq, Jul 2008]

The c.649C>T (p.R217C) alteration is located in exon 4 (coding exon 4) of the CLEC11A gene. This alteration results from a C to T substitution at nucleotide position 649, causing the arginine (R) at amino acid position 217 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
