Genes affected

ALCAM (HGNC:400): (activated leukocyte cell adhesion molecule) This gene encodes activated leukocyte cell adhesion molecule (ALCAM), also known as CD166 (cluster of differentiation 166), which is a member of a subfamily of immunoglobulin receptors with five immunoglobulin-like domains (VVC2C2C2) in the extracellular domain. This protein binds to T-cell differentiation antigene CD6, and is implicated in the processes of cell adhesion and migration. Multiple alternatively spliced transcript variants encoding different isoforms have been found. [provided by RefSeq, Aug 2011]

May 09, 2023

The c.245A>T (p.D82V) alteration is located in exon 3 (coding exon 3) of the ALCAM gene. This alteration results from a A to T substitution at nucleotide position 245, causing the aspartic acid (D) at amino acid position 82 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
