Endove syndrome, limb-brain type(ENDOVESLB; MLEHFB)

MedGen UID:
1782954
Concept ID:
C5543142
Disease or Syndrome
Synonym: MESOMELIA OF LOWER EXTREMITIES WITH HAND, FOOT, AND BRAIN ANOMALIES
 
Gene (location): EN1 (2q14.2)
 
Monarch Initiative: MONDO:0030979
OMIM®: 619218

Definition

Limb-brain ENDOVE syndrome (ENDOVESLB) is characterized by marked mesomelic shortening of the lower limbs due to severe hypoplasia of the tibia and fibula. The talus is absent and foot bones are rudimentary. Hands show short and malformed fingers with a missing digit, and nails are absent on some fingers. In addition, there is cerebellar aplasia with hypoplasia of the brainstem (Allou et al., 2021). [from OMIM]

Clinical features

From HPO
Neurogenic bladder
MedGen UID:
595
Concept ID:
C0005697
Disease or Syndrome
A type of bladder dysfunction caused by neurologic damage. Neurogenic bladder can be flaccid or spastic. Common manifestatios of neurogenic bladder are overflow incontinence, frequency, urgency, urge incontinence, and retention.
Hydronephrosis
MedGen UID:
42531
Concept ID:
C0020295
Disease or Syndrome
Severe distention of the kidney with dilation of the renal pelvis and calices.
Recurrent urinary tract infections
MedGen UID:
120466
Concept ID:
C0262655
Disease or Syndrome
Repeated infections of the urinary tract.
Toe syndactyly
MedGen UID:
75581
Concept ID:
C0265660
Congenital Abnormality
Webbing or fusion of the toes, involving soft parts only or including bone structure. Bony fusions are referred to as "bony" Syndactyly if the fusion occurs in a radio-ulnar axis. Fusions of bones of the toes in a proximo-distal axis are referred to as "Symphalangism".
Aplasia of the 3rd finger
MedGen UID:
869915
Concept ID:
C4024346
Finding
Absent 3rd finger.
Triangular tibia
MedGen UID:
1612259
Concept ID:
C4531241
Anatomical Abnormality
A short, dysplastic tibia with a triangular shape. Instead of the normal shaft configuration of the tibia, the tibia forms a triangle with the longest side corresponding to the proximal-distal dimension, and the apex of the triangle directed laterally.
Talar aplasia
MedGen UID:
1813979
Concept ID:
C5553008
Congenital Abnormality
Absent talus owing to a congenital defect.
Failure to thrive
MedGen UID:
746019
Concept ID:
C2315100
Disease or Syndrome
Failure to thrive (FTT) refers to a child whose physical growth is substantially below the norm.
Gastrojejunal tube feeding in infancy
MedGen UID:
896852
Concept ID:
C4280681
Finding
Feeding problem necessitating gastrojejunal tube feeding.
Delayed speech and language development
MedGen UID:
105318
Concept ID:
C0454644
Finding
A degree of language development that is significantly below the norm for a child of a specified age.
Focal tonic seizure
MedGen UID:
199867
Concept ID:
C0752324
Disease or Syndrome
A type of focal motor seizure characterized by sustained increase in muscle contraction, lasting a few seconds to minutes.
Persistent head lag
MedGen UID:
256151
Concept ID:
C1141883
Finding
The Premie-Neuro and the Dubowitz Neurological Examination score head lag in the same manner. Scoring for both is as follows
Hypoplasia of the brainstem
MedGen UID:
334226
Concept ID:
C1842688
Finding
Underdevelopment of the brainstem.
Cerebellar agenesis
MedGen UID:
868414
Concept ID:
C4022808
Congenital Abnormality
Cerebellar agenesis is defined by the near complete absence of cerebellar tissue with only remnants of the anterior vermis, flocculus, and/or middle cerebellar peduncles.
Umbilical hernia
MedGen UID:
9232
Concept ID:
C0019322
Anatomical Abnormality
Protrusion of abdominal contents through a defect in the abdominal wall musculature around the umbilicus. Skin and subcutaneous tissue overlie the defect.
Hypotonia
MedGen UID:
10133
Concept ID:
C0026827
Finding
Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.
Joint hypermobility
MedGen UID:
336793
Concept ID:
C1844820
Finding
The capability that a joint (or a group of joints) has to move, passively and/or actively, beyond normal limits along physiological axes.
Generalized hypotonia
MedGen UID:
346841
Concept ID:
C1858120
Finding
Generalized muscular hypotonia (abnormally low muscle tone).
Microcephaly
MedGen UID:
1644158
Concept ID:
C4551563
Finding
Head circumference below 2 standard deviations below the mean for age and gender.
Osteomyelitis
MedGen UID:
10497
Concept ID:
C0029443
Disease or Syndrome
Osteomyelitis is an inflammatory process accompanied by bone destruction and caused by an infecting microorganism.
