Pallister-W syndrome

MedGen UID:
163215
Concept ID:
C0796110
Disease or Syndrome
Synonyms: Median cleft upper lip, mental retardation and pugilistic facies; W syndrome
SNOMED CT: Pallister W syndrome (719020006); W syndrome (719020006)
Modes of inheritance:
X-linked recessive inheritance
MedGen UID:
375779
Concept ID:
C1845977
Finding
Source: Orphanet
A mode of inheritance that is observed for recessive traits related to a gene encoded on the X chromosome. In the context of medical genetics, X-linked recessive disorders manifest in males (who have one copy of the X chromosome and are thus hemizygotes), but generally not in female heterozygotes who have one mutant and one normal allele.

Definition

A rare multiple congenital anomalies/dysmorphic syndrome with characteristics of moderate to severe intellectual disability, neurologic signs and symptoms (such as seizures, spasticity, strabismus), characteristic dysmorphic facial features (including broad forehead, hypertelorism, downslanting palpebral fissures, broad and flat nasal bridge, midline notch of upper lip, lack of upper central incisors, incomplete oral cleft, and prominent mandible), and acne scars. Hearing impairment, pseudo-bulbar palsy, growth retardation, and skeletal anomalies (camptodactyly, clinodactyly, bilateral cubitus valgus, pes cavus/planus) has also been described. [from SNOMEDCT_US]

Clinical features

From HPO
Pes planus
MedGen UID:
42034
Concept ID:
C0016202
Anatomical Abnormality
A foot where the longitudinal arch of the foot is in contact with the ground or floor when the individual is standing; or, in a patient lying supine, a foot where the arch is in contact with the surface of a flat board pressed against the sole of the foot by the examiner with a pressure similar to that expected from weight bearing; or, the height of the arch is reduced.
Hypertelorism
MedGen UID:
9373
Concept ID:
C0020534
Finding
Although hypertelorism means an excessive distance between any paired organs (e.g., the nipples), the use of the word has come to be confined to ocular hypertelorism. Hypertelorism occurs as an isolated feature and is also a feature of many syndromes, e.g., Opitz G syndrome (see 300000), Greig cephalopolysyndactyly (175700), and Noonan syndrome (163950) (summary by Cohen et al., 1995).
Spasticity
MedGen UID:
7753
Concept ID:
C0026838
Sign or Symptom
A motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes with increased muscle tone, exaggerated (hyperexcitable) tendon reflexes.
Seizure
MedGen UID:
20693
Concept ID:
C0036572
Sign or Symptom
A seizure is an intermittent abnormality of nervous system physiology characterised by a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.
Alternating esotropia
MedGen UID:
57515
Concept ID:
C0152205
Disease or Syndrome
Esotropia in which either eye may be used for fixation.
Joint contracture of the hand
MedGen UID:
56382
Concept ID:
C0158113
Finding
Contractures of one ore more joints of the hands meaning chronic loss of joint motion due to structural changes in non-bony tissue.
Cubitus valgus
MedGen UID:
490152
Concept ID:
C0158465
Acquired Abnormality
Abnormal positioning in which the elbows are turned out.
Frontal bossing
MedGen UID:
67453
Concept ID:
C0221354
Congenital Abnormality
Bilateral bulging of the lateral frontal bone prominences with relative sparing of the midline.
Downslanted palpebral fissures
MedGen UID:
98391
Concept ID:
C0423110
Finding
The palpebral fissure inclination is more than two standard deviations below the mean.
Telecanthus
MedGen UID:
140836
Concept ID:
C0423113
Finding
Distance between the inner canthi more than two standard deviations above the mean (objective); or, apparently increased distance between the inner canthi.
Broad nasal tip
MedGen UID:
98424
Concept ID:
C0426429
Finding
Increase in width of the nasal tip.
Submucous cleft hard palate
MedGen UID:
98472
Concept ID:
C0432103
Congenital Abnormality
Hard-palate submucous clefts are characterized by bony defects in the midline of the bony palate that are covered by the mucous membrane of the roof of the mouth. It may be possible to detect a submucous cleft hard palate upon palpation as a notch in the bony palate.
Camptodactyly
MedGen UID:
195780
Concept ID:
C0685409
Congenital Abnormality
The distal interphalangeal joint and/or the proximal interphalangeal joint of the fingers or toes cannot be extended to 180 degrees by either active or passive extension.
Pes cavus
MedGen UID:
675590
Concept ID:
C0728829
Congenital Abnormality
The presence of an unusually high plantar arch. Also called high instep, pes cavus refers to a distinctly hollow form of the sole of the foot when it is bearing weight.
Frontal upsweep of hair
MedGen UID:
452910
Concept ID:
C1185616
Finding
Upward and/or sideward growth of anterior hair.
Radial deviation of finger
MedGen UID:
322852
Concept ID:
C1836189
Finding
Bending or curvature of a finger toward the radial side (i.e., towards the thumb). The deviation is at the metacarpal-phalangeal joint, and this finding is distinct from clinodactyly.
Depressed nasal bridge
MedGen UID:
373112
Concept ID:
C1836542
Finding
Posterior positioning of the nasal root in relation to the overall facial profile for age.
Wide nasal bridge
MedGen UID:
341441
Concept ID:
C1849367
Finding
Increased breadth of the nasal bridge (and with it, the nasal root).
Agenesis of central incisor
MedGen UID:
381532
Concept ID:
C1855000
Finding
Agenesis of one or more central incisors, i.e., of lower secondary incisor, lower primary incisor, upper secondary incisor, or of upper central primary incisor.
Radial bowing
MedGen UID:
347136
Concept ID:
C1859399
Anatomical Abnormality
A bending or abnormal curvature of the radius.
Hypoplasia of the ulna
MedGen UID:
395934
Concept ID:
C1860614
Congenital Abnormality
Underdevelopment of the ulna.
Broad uvula
MedGen UID:
786050
Concept ID:
C3693299
Finding
Increased width of the uvula (subjective finding).
Intellectual disability
MedGen UID:
811461
Concept ID:
C3714756
Mental or Behavioral Dysfunction
Subnormal intellectual functioning which originates during the developmental period. Intellectual disability, previously referred to as mental retardation, has been defined as an IQ score below 70.
Agenesis of maxillary central incisor
MedGen UID:
870617
Concept ID:
C4025068
Finding
Agenesis of upper secondary incisor or of upper central primary incisor.
Metatarsus adductus
MedGen UID:
898667
Concept ID:
C4082169
Anatomical Abnormality
The metatarsals are deviated medially (tibially), that is, the bones in the front half of the foot bend or turn in toward the body.
Clinodactyly
MedGen UID:
1644094
Concept ID:
C4551485
Congenital Abnormality
An angulation of a digit at an interphalangeal joint in the plane of the palm (finger) or sole (toe).
