Red List (low evidence)

The Houge type of X-linked syndromic intellectual developmental disorder (MRXSHG) is characterized by delayed development, intellectual disability, speech and language delay, and early-onset seizures. EEG tends to show continuous spike-wave activity or centrotemporal spikes. Some patients may have remission of seizures by adolescence. Carrier females may be mildly affected. 13 new families and literature review in PMID 34266427.

Unlikely to be detected antenatally.
