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]

The c.814A>G (p.I272V) alteration is located in exon 12 (coding exon 12) of the CD99L2 gene. This alteration results from a A to G substitution at nucleotide position 814, causing the isoleucine (I) at amino acid position 272 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
