Stickler syndrome, type 6(STL6)

MedGen UID:
1823980
Concept ID:
C5774207
Disease or Syndrome
Synonyms: Stickler syndrome, IIa 6; Stickler syndrome, type VI
 
Gene (location): COL9A3 (20q13.33)
 
Monarch Initiative: MONDO:0031047
OMIM®: 620022

Definition

Stickler syndrome type VI (STL6) is characterized by early-onset progressive hearing loss and progressive myopia, with variable manifestation of facial dysmorphism and skeletal anomalies (Nixon et al., 2019; Rad et al., 2022). For a general phenotypic description and discussion of genetic heterogeneity of Stickler syndrome, see STL1 (108300). [from OMIM]

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.
Internal tibial torsion

Intellectual disability
MedGen UID:
811461
Concept ID:

Intellectual disability, previously referred to as mental retardation, is characterized by subnormal intellectual functioning that occurs during the developmental period. It is defined by an IQ score below 70.
Downslanted palpebral fissures
MedGen UID:
98391
Concept ID:

The palpebral fissure inclination is more than two standard deviations below the mean.
Depressed nasal bridge

Finding
Posterior positioning of the nasal root in relation to the overall facial profile for age.
Midface retrusion
MedGen UID:
339938
Concept ID:
C1853242
Anatomical Abnormality
Posterior positions and/or vertical shortening of the infraorbital and perialar regions, or increased concavity of the face and/or reduced nasolabial angle.
Astigmatism
MedGen UID:
2473
Concept ID:
C0004106
Disease or Syndrome
Astigmatism (from the Greek 'a' meaning absence and 'stigma' meaning point) is a condition in which the parallel rays of light entering the eye through the refractive media are not focused on a single point. Both corneal and noncorneal factors contribute to refractive astigmatism. Corneal astigmatism is mainly the result of an aspheric anterior surface of the cornea, which can be measured readily by means of a keratometer; in a small fraction of cases (approximately 1 in 10) the effect is neutralized by the back surface. The curvature of the back surface of the cornea is not considered in most studies, because it is more difficult to measure; moreover, in the case of severe corneal astigmatism, there is evidence that both surfaces have the same configuration. Noncorneal factors are errors in the curvature of the 2 surfaces of the crystalline lens, irregularity in the refractive index of the lens, and an eccentric lens position. Since the cornea is the dominant component of the eye's refracting system, a highly astigmatic cornea is likely to result in a similarly astigmatic ocular refraction (summary by Clementi et al., 1998).
Ptosis
MedGen UID:
2287
Concept ID:
C0005745
Disease or Syndrome
The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective).
High myopia
MedGen UID:
78759
Concept ID:
C0271183
Disease or Syndrome
A severe form of myopia with greater than -6.00 diopters.
Moderate myopia
MedGen UID:
939834
Concept ID:
C4315867
Disease or Syndrome
A moderate form of myopia with refractive error of between -3.00 and -6.00 diopters.
