Overview
Atrichia-intellectual disability and growth delay syndrome is an extremely rare genetic condition that has been described in only a very small number of individuals in the medical literature. The term 'OBSOLETE' in its name indicates that this condition may have been reclassified or merged with another diagnosis as medical understanding has advanced. The syndrome was originally characterized by three main features: atrichia (absence or severe loss of hair), intellectual disability (difficulties with learning and thinking), and growth delay (slower than expected physical growth during childhood). Affected individuals may be born with little or no hair, and this hair loss tends to be permanent. Children with this condition may show delays in reaching developmental milestones such as sitting, walking, and talking. Physical growth, including height and weight, may fall below what is expected for their age. Because this condition is so rare, the treatment approach has been largely supportive, focusing on managing individual symptoms. This may include special education services for intellectual disability, growth monitoring, and dermatological care for skin and hair concerns. There is currently no cure or specific targeted therapy for this syndrome.
Key symptoms:
Absence or severe loss of hair from birthIntellectual disability or learning difficultiesSlower than expected physical growthShort statureDelayed developmental milestonesPossible skin abnormalitiesLow body weight for ageDelayed speech developmentDelayed motor skills such as walking
Autosomal recessive
Passed on when both parents carry the same gene change; often skips generations
Neonatal
Begins at or shortly after birth (first 4 weeks)
