Genes affected

HRK (HGNC:5185): (harakiri, BCL2 interacting protein) This gene encodes a member of the BCL-2 protein family. Members of this family are involved in activating or inhibiting apoptosis. The encoded protein localizes to intracellular membranes. This protein promotes apoptosis by interacting with the apoptotic inhibitors BCL-2 and BCL-X(L) via its BH3 domain. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2012]

HRK (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3141853).

Sep 17, 2021

The c.17T>C (p.L6P) alteration is located in exon 1 (coding exon 1) of the HRK gene. This alteration results from a T to C substitution at nucleotide position 17, causing the leucine (L) at amino acid position 6 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
