Genes affected

TSSC4 (HGNC:12386): (tumor suppressing subtransferable candidate 4) This gene is one of several tumor-suppressing subtransferable fragments located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocortical carcinoma, and lung, ovarian, and breast cancer. This gene is located among several imprinted genes; however, this gene, as well as the pan-hematopoietic expression gene (PHEMX), escapes imprinting. This gene may play a role in malignancies and disease that involve this region. Several transcript variants encoding two different isoforms have been found for this gene.

The c.194C>T (p.P65L) alteration is located in exon 2 (coding exon 1) of the TSSC4 gene. This alteration results from a C to T substitution at nucleotide position 194, causing the proline (P) at amino acid position 65 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
