Distal arthrogryposis Type 1 Overview Distal arthrogryposis type 1 is a rare genetic condition that causes non-progressive joint contractures (stiffness and deformities) primarily restricting movement in the hands and feet. It typically does not affect intelligence or involve internal organs. Symptoms Hand and Finger Symptoms Camptodactyly : Permanently bent or flexed fingers that cannot straighten completely. Overlapping fingers: Fingers that cross over one another when the hands are at rest. Ulnar deviation: A hand deformity where the fingers angle outward toward the pinky (fifth) finger. Clasped thumbs: Thumbs pulled tightly across the palm. Foot and Toe Symptoms Clubfoot: Feet that turn inward and upward (talipes equinovarus). Bent toes: Permanently flexed or overlapping toes similar to the finger deformities. General Characteristics Localized impact: Contractures are mostly limited to the distal limbs (hands, wrists, feet). Normal intelligence: Cognitive development and intell...
Beta-ketothiolase deficiency Overview Beta-ketothiolase deficiency is a rare inherited metabolic disorder that stops the body from properly processing the amino acid isoleucine and ketone bodies. Caused by mutations in the ACAT1 gene, it leads to harmful ketoacidotic crises triggered by fasting or common infections Symptoms Signs of a Metabolic Crises Children with this condition are typically healthy between episodes, but attacks can be triggered by infections, fasting, or high-protein meals. Common signs include: Severe vomiting and poor appetitee Extreme lack of energy or sleepiness (lethargy)Trouble breathing or fast breathing (tachypnea)Dehydration Unusual fruity or sweet-smelling breath/urine Seizures or convulsionss Loss of consciousness or coma in severe cases Long-Term Effects Most children recover quickly if treated during an attack.Repeated or severe untreated crises can lead to developmental delays or intellectual disability.Symptoms often become less frequent or severe as ...
