BIDS syndrome, also called nonphotosensitive trichothiodystrophy 1 (TTND1), Amish brittle hair brain syndrome and hair-brain syndrome,[1] is an autosomal recessive[2] genodermatosis similar to IBIDS syndrome but without the ichthyosiform changes. BIDS is characterized by brittle hair, intellectual impairment, decreased fertility, and short stature.[3]:501

It is associated with C7ORF11.[4]
