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]

HYPK links:

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]

Collection Method: clinical testing

The c.36G>C (p.E12D) alteration is located in exon 1 (coding exon 1) of the HYPK gene. This alteration results from a G to C substitution at nucleotide position 36, causing the glutamic acid (E) at amino acid position 12 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
