Mental retardation and microcephaly with pontine and cerebellar hypoplasia (MICPCH), also known as mental retardation, X-linked, syndromic, Najm type (MRXSNA) and X-linked intellectual deficit, Najm type, is a rare X-linked dominant genetic disorder of infants characterised by intellectual disability and pontocerebellar hypoplasia. It usually affects females; many males die before birth or not long after.[2]

The disorder is associated with a mutation in the CASK gene.[3] As with the vast majority of genetic disorders, there is no known cure to MICPCH.[citation needed]

The following values seem to be aberrant in children with CASK gene defects: lactate, pyruvate, 2-ketoglutarate, adipic acid and suberic acid, which seems to backup the proposal that CASK affects mitochondrial function.[4] It is also speculated that phosphoinositide 3-kinase in the inositol metabolism is impacted in the disease, causing folic acid metabolization problems.[citation needed]
