Genes affected
KCNH5 (HGNC:6254): (potassium voltage-gated channel subfamily H member 5) This gene encodes a member of voltage-gated potassium channels. Members of this family have diverse functions, including regulating neurotransmitter and hormone release, cardiac function, and cell volume. This protein is an outward-rectifying, noninactivating channel. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KCNH5. . Gene score misZ 2.509 (greater than the threshold 3.09). Trascript score misZ 3.7308 (greater than threshold 3.09). GenCC has associacion of gene with infantile-onset epilepsy.
BP4
Computational evidence support a benign effect (MetaRNN=0.049616843).
BP6
Variant 14-62708239-A-G is Benign according to our data. Variant chr14-62708239-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 530451.Status of the report is criteria_provided_single_submitter, 1 stars.
BS2
High AC in GnomAd4 at 34 AD gene.
