Genes affected
LHX4 (HGNC:21734): (LIM homeobox 4) This gene encodes a member of a large protein family which contains the LIM domain, a unique cysteine-rich zinc-binding domain. The encoded protein is a transcription factor involved in the control of differentiation and development of the pituitary gland. Mutations in this gene cause combined pituitary hormone deficiency 4. [provided by RefSeq, Dec 2010]
ACBD6 (HGNC:23339): (acyl-CoA binding domain containing 6) Predicted to enable fatty-acyl-CoA binding activity and lipid binding activity. Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]
