Genes affected

TPD52L1 (HGNC:12006): (TPD52 like 1) This gene encodes a member of a family of proteins that contain coiled-coil domains and may form hetero- or homomers. The encoded protein is involved in cell proliferation and calcium signaling. It also interacts with the mitogen-activated protein kinase kinase kinase 5 (MAP3K5/ASK1) and positively regulates MAP3K5-induced apoptosis. Multiple alternatively spliced transcript variants have been observed. [provided by RefSeq, Jan 2016]

HDDC2 (HGNC:21078): (HD domain containing 2) Predicted to enable 5'-deoxynucleotidase activity. Predicted to be involved in dephosphorylation. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
