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.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.76).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0136 (2071/152288) while in subpopulation NFE AF= 0.0215 (1462/68004). AF 95% confidence interval is 0.0206. There are 25 homozygotes in gnomad4. There are 984 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 24 AR gene
