Genes affected

NEXMIF (HGNC:29433): (neurite extension and migration factor) An inversion on the X chromosome which disrupts this gene and a G-protein coupled purinergic receptor gene located in the pseudoautosomal region of the X chromosome has been linked to X linked cognitive disability.[provided by RefSeq, Mar 2009]

NEXMIF Gene-Disease associations (from GenCC):

• X-linked complex neurodevelopmental disorder

  Inheritance: XL Classification: DEFINITIVE Submitted by: ClinGen
• X-linked intellectual disability, Cantagrel type

  Inheritance: XL Classification: STRONG, SUPPORTIVE Submitted by: Orphanet, Labcorp Genetics (formerly Invitae)
