Genes affected

CD99L2 (HGNC:18237): (CD99 molecule like 2) This gene encodes a cell-surface protein that is similar to CD99. A similar protein in mouse functions as an adhesion molecule during leukocyte extravasation. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.616G>A (p.V206I) alteration is located in exon 9 (coding exon 9) of the CD99L2 gene. This alteration results from a G to A substitution at nucleotide position 616, causing the valine (V) at amino acid position 206 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
