Genes affected
KLHDC8B (HGNC:28557): (kelch domain containing 8B) This gene encodes a protein which forms a distinct beta-propeller protein structure of kelch domains allowing for protein-protein interactions. Mutations in this gene have been associated with Hodgkin lymphoma. [provided by RefSeq, Sep 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.62).
BP6
Variant 3-49172991-G-A is Benign according to our data. Variant chr3-49172991-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3032566.Status of the report is no_assertion_criteria_provided, 0 stars.
BP7
Synonymous conserved (PhyloP=-2.34 with no splicing effect.
BS2
High AC in GnomAdExome4 at 10 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
