Official Full Name: hyccin PI4KA lipid kinase complex subunit 1provided by HGNC
Primary source: HGNC:HGNC:24587
See related: Ensembl:ENSG00000122591 MIM:610531; AllianceGenome:HGNC:24587
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: HCC; HLD5; FAM126A; DRCTNNB1A
Summary: The protein encoded by this gene may play a part in the beta-catenin/Lef signaling pathway. Expression of this gene is down-regulated by beta-catenin. Defects in this gene are a cause of hypomyelination with congenital cataract (HCC). [provided by RefSeq, Oct 2008]
Expression: Ubiquitous expression in lymph node (RPKM 7.3), testis (RPKM 6.5) and 25 other tissues See more

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.
