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 GeneticsJun 26, 2024The c.745C>T (p.P249S) alteration is located in exon 11 (coding exon 11) of the CD99L2 gene. This alteration results from a C to T substitution at nucleotide position 745, causing the proline (P) at amino acid position 249 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
