Genes affected

HYPK (HGNC:18418): (huntingtin interacting protein K) Enables protein N-terminus binding activity. Involved in negative regulation of apoptotic process and protein stabilization. Located in cytoplasm; microtubule cytoskeleton; and nucleoplasm. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

SERF2 (HGNC:10757): (small EDRK-rich factor 2) Involved in protein destabilization. Predicted to be located in cytosol and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

SERF2-C15ORF63 (HGNC:):

ACMG classification

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

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