Genes affected
ANKRD31 (HGNC:26853): (ankyrin repeat domain 31) This gene encodes a protein containing multiple ankyrin repeats. Ankyrin domains function in protein-protein interactions in a variety of cellular processes. Mutations in this gene are associated with a Rett syndrome (RTT)-like phenotype.
