Variant 6-138406150-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_014320.3(HEBP2):c.418C>T(p.Arg140Trp) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00007 in 1,613,218 control chromosomes in the GnomAD database, with no homozygous occurrence. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R140Q) has been classified as Likely benign.

Genes affected

HEBP2 (HGNC:15716): (heme binding protein 2) The protein encoded by this gene is found predominately in the cytoplasm, where it plays a role in the collapse of mitochondrial membrane potential (MMP) prior to necrotic cell death. The encoded protein enhances outer and inner mitochondrial membrane permeabilization, especially under conditions of oxidative stress. [provided by RefSeq, May 2016]

Ambry Genetics

Apr 07, 2022

The c.418C>T (p.R140W) alteration is located in exon 3 (coding exon 3) of the HEBP2 gene. This alteration results from a C to T substitution at nucleotide position 418, causing the arginine (R) at amino acid position 140 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
