What's a GeneRIF?

Kctd7 deficiency induces myoclonic seizures associated with Purkinje cell death and microvascular defects.
Title: Kctd7 deficiency induces myoclonic seizures associated with Purkinje cell death and microvascular defects.
Deletion of Kctd7 induces defective patterning of the adult mouse retina vascular network, resulting in increased branching, vessel length, and lacunarity. These alterations reflect early and specific defects in vessel development, as emergence of the superficial and deep vascular layers were delayed. These defects are likely due to a role for Kctd7 in inner retina neurons.
Title: Progressive myoclonic epilepsy-associated gene Kctd7 regulates retinal neurovascular patterning and function.
KCTD7 expression hyperpolarizes the cell membrane and reduces the excitability of transfected neurons in patch clamp experiments.
Title: Progressive myoclonic epilepsy-associated gene KCTD7 is a regulator of potassium conductance in neurons.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
