Genes affected

TPD52L2 (HGNC:12007): (TPD52 like 2) This gene encodes a member of the tumor protein D52-like family. These proteins are characterized by an N-terminal coiled-coil motif that is used to form homo- and heteromeric complexes with other tumor protein D52-like proteins. Expression of this gene may be a marker for breast cancer and acute lymphoblastic leukemia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 12.

The c.578G>A (p.R193Q) alteration is located in exon 8 (coding exon 8) of the TPD52L2 gene. This alteration results from a G to A substitution at nucleotide position 578, causing the arginine (R) at amino acid position 193 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
