Medium match SUCCINIC SEMIALDEHYDE DEHYDROGENASE DEFICIENCY; SSADHD

Succinic semialdehyde dehydrogenase deficiency (SSADHD) is a rare autosomal recessive neurologic disorder in which an enzyme defect in the GABA degradation pathway causes a consecutive elevation of gamma-hydroxybutyric acid (GHB) and GABA. The clinical features include developmental delay, hypotonia, mental retardation, ataxia, seizures, hyperkinetic behavior, aggression, and sleep disturbances (summary by Reis et al., 2012).

SUCCINIC SEMIALDEHYDE DEHYDROGENASE DEFICIENCY; SSADHD Is also known as ssadh deficiency, 4-hydroxybutyric aciduria, gaba metabolic defect, gamma-hydroxybutyric aciduria;4-hydroxybutyric aciduria; gamma-hydroxybutyric aciduria; ssadh deficiency

Related symptoms:

  • Autosomal recessive inheritance
  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Generalized hypotonia

Medium match EPILEPSY, PYRIDOXINE-DEPENDENT; EPD

Pyridoxine-dependent epilepsy, characterized by a combination of various seizure types, usually occurs in the first hours of life and is unresponsive to standard anticonvulsants, responding only to immediate administration of pyridoxine hydrochloride. The dependence is permanent, and the interruption of daily pyridoxine supplementation leads to the recurrence of seizures. Some patients show developmental delay. The prevalence is estimated at 1 in 400,000 to 700,000 (Bennett et al., 2005).

EPILEPSY, PYRIDOXINE-DEPENDENT; EPD Is also known as pyridoxine-dependent epilepsy;pde, pyridoxine dependency with seizures, aasa dehydrogenase deficiency

Related symptoms:

  • Autosomal recessive inheritance
  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Generalized hypotonia

Medium match MENTAL RETARDATION, X-LINKED, SYNDROMIC, HEDERA TYPE; MRXSH

X-linked intellectual disability, Hedera type is a rare X-linked intellectual disability syndrome characterized by an onset in infancy of delayed motor and speech milestones, generalized tonic-clonic seizures and drop attacks, and mild to moderate intellectual disability. Additional, less common manifestations include scoliosis, ataxia (resulting in progressive gait disturbance), and bilateral pes planovalgus. Physical appearance is normal with no dysmorphic features reported.

MENTAL RETARDATION, X-LINKED, SYNDROMIC, HEDERA TYPE; MRXSH Is also known as mental retardation, x-linked, with epilepsy;mrxe;mrxsh

Medium match EPILEPTIC ENCEPHALOPATHY, EARLY INFANTILE, 9; EIEE9

Female restricted epilepsy with intellectual disability is a rare X-linked epilepsy syndrome characterized by febrile or afebrile seizures (mainly tonic-clonic, but also absence, myoclonic, and atonic) starting in the first years of life and, in most cases, developmental delay and intellectual disability of variable severity. Behavioral disturbances (e.g. autistic features, hyperactivity, and aggressiveness) are also frequently associated. This disease affects exclusively females, with male carriers being unaffected, despite an X-linked inheritance.

EPILEPTIC ENCEPHALOPATHY, EARLY INFANTILE, 9; EIEE9 Is also known as epilepsy, female-restricted, with mental retardation;efmr, juberg-hellman syndrome;efmr; juberg-hellman syndrome
