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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 23, 2024The c.712G>A (p.G238R) alteration is located in exon 11 (coding exon 11) of the CD99L2 gene. This alteration results from a G to A substitution at nucleotide position 712, causing the glycine (G) at amino acid position 238 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
