Genes affected

DCST2 (HGNC:26562): (DC-STAMP domain containing 2) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

DCST2 links:

ZBTB7B (HGNC:18668): (zinc finger and BTB domain containing 7B) This gene encodes a zinc finger-containing transcription factor that acts as a key regulator of lineage commitment of immature T-cell precursors. It is necessary and sufficient for commitment of CD4 lineage, while its absence causes CD8 commitment. It also functions as a transcriptional repressor of type I collagen genes. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012]
