Genes affected

DPP6 (HGNC:3010): (dipeptidyl peptidase like 6) This gene encodes a single-pass type II membrane protein that is a member of the peptidase S9B family of serine proteases. This protein has no detectable protease activity, most likely due to the absence of the conserved serine residue normally present in the catalytic domain of serine proteases. However, it does bind specific voltage-gated potassium channels and alters their expression and biophysical properties. Variations in this gene may be associated with susceptibility to amyotrophic lateral sclerosis and with idiopathic ventricular fibrillation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PP5: Variant 7-154305155-C-T is Pathogenic according to our data. Variant chr7-154305155-C-T is described in ClinVar as [Pathogenic, risk_factor]. Clinvar id is 16794.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr7-154305155-C-T is described in Lovd as [Likely_pathogenic]. Variant chr7-154305155-C-T is described in Lovd as [Pathogenic].
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.47).. Strength limited to SUPPORTING due to the PP5.
