Lethal occipital encephalocele-skeletal dysplasia syndrome(RHFCA)

MedGen UID:
482359
Concept ID:
C3280729
Disease or Syndrome
Synonym: Radiohumeral fusions with other skeletal and craniofacial anomalies
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
Concept ID:
C0441748
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
 
Gene (location): CYP26B1 (2p13.2)
 
Monarch Initiative: MONDO:0013740
OMIM®: 614416
Orphanet: ORPHA293925

Definition

Lethal occipital encephalocele-skeletal dysplasia syndrome is a rare, genetic, bone development disorder characterized by occipital and parietal bone hypoplasia leading to occipital encephalocele, calvarial mineralization defects, craniosynostosis, radiohumeral fusions, oligodactyly and other skeletal anomalies (arachnodactyly, terminal phalangeal aplasia of the thumbs, bilateral absence of the great toes, pronounced bilateral angulation of femora, shortened limbs, advanced osseous maturation). Fetal death in utero is associated. [from ORDO]

Clinical features

From HPO
Arachnodactyly
MedGen UID:
2047
Concept ID:
C0003706
Congenital Abnormality
Abnormally long and slender fingers ("spider fingers").
Humeroradial synostosis
MedGen UID:
418931
Concept ID:
C2930865
Disease or Syndrome
An abnormal osseous union (fusion) between the radius and the humerus.
Oligodactyly
MedGen UID:
854358
Concept ID:
C3887496
Congenital Abnormality
A developmental defect resulting in the presence of fewer than the normal number of digits.
Occipital encephalocele
MedGen UID:
4935
Concept ID:
C0014067
Congenital Abnormality
A type of encephalocele (that is, a a protrusion of part of the cranial contents including brain tissue through a congenital opening in the cranium, typically covered with skin or mucous membrane) in the occipital region of the skull. Occipital encephalocele presents as a midline swelling over the occipital bone. It is usually covered with normal full-thickness scalp.
Craniosynostosis syndrome
MedGen UID:
1163
Concept ID:
C0010278
Disease or Syndrome
Craniosynostosis refers to the premature closure of the cranial sutures. Primary craniosynostosis refers to the closure of one or more sutures due to abnormalities in skull development, and secondary craniosynostosis results from failure of brain growth.
Brachycephaly
MedGen UID:
113165
Concept ID:
C0221356
Congenital Abnormality
An abnormality of skull shape characterized by a decreased anterior-posterior diameter. That is, a cephalic index greater than 81%. Alternatively, an apparently shortened anteroposterior dimension (length) of the head compared to width.
