Variant names:

• chr15-43801787-T-A
• rs61744182
• NM_016400.4:c.347T>A

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_016400.4(HYPK):​c.347T>A​(p.Leu116His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L116R) has been classified as Uncertain significance.

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:):
