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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.295A>G (p.M99V) alteration is located in exon 4 (coding exon 4) of the HYPK gene. This alteration results from a A to G substitution at nucleotide position 295, causing the methionine (M) at amino acid position 99 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
