Genes affected

ZNHIT3 (HGNC:12309): (zinc finger HIT-type containing 3) Predicted to enable thyroid hormone receptor binding activity. Predicted to be involved in box C/D snoRNP assembly; maturation of LSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA); and snoRNA localization. Located in cytoplasm and nucleus. Implicated in PEHO syndrome. [provided by Alliance of Genome Resources, Apr 2022]

LOC105371749 (HGNC:):
