Presentation
Presumably because of the basic defect present in CHST3-related skeletal dysplasia, surgical correction is often only partially successful and most patients have had multiple procedures by adulthood [Unger et al 2010]. [ncbi.nlm.nih.gov]
Entire Body System
- Single Transverse Palmar Crease
Bilateral single transverse palmar creases MedGen UID: 354661 •Concept ID: C1862095 • Finding The distal and proximal transverse palmar creases are merged into a single transverse palmar crease on both hands. [ncbi.nlm.nih.gov]
Jaw & Teeth
- Widely Spaced Teeth
Widely spaced teeth MedGen UID: 337093 •Concept ID: C1844813 • Finding Increased spaces (diastemata) between most of the teeth in the same dental arch. [ncbi.nlm.nih.gov]
Skin

Ears
- Hearing Impairment
Hearing impairment MedGen UID: 235586 •Concept ID: C1384666 • Disease or Syndrome A general term for the complete or partial loss of the ability to hear from one or both ears. [ncbi.nlm.nih.gov]
Musculoskeletal
- Arthralgia
Arthralgia MedGen UID: 13917 •Concept ID: C0003862 • Sign or Symptom Joint pain. Clubfoot MedGen UID: 3130 •Concept ID: C0009081 • Congenital Abnormality A deformed foot in which the foot is plantarflexed, inverted, and adducted. [ncbi.nlm.nih.gov]
- Flexion Contracture
Flexion contracture MedGen UID: 83069 •Concept ID: C0333068 • Anatomical Abnormality A flexion contracture is a bent (flexed) joint that cannot be straightened actively or passively. [ncbi.nlm.nih.gov]
- Genu Valgum
Genu valgum can develop due to skeletal and joint dysplasias (e.g., OSTEOARTHRITIS; HURLER SYNDROME); and malnutrition (e.g., RICKETS; FLUORIDE POISONING). [ncbi.nlm.nih.gov]
Face, Head & Neck
- Short Neck
Short femoral neck MedGen UID: 373033 •Concept ID: C1836184 • Finding An abnormally short femoral neck (which is the process of bone, connecting the femoral head with the femoral shaft). [ncbi.nlm.nih.gov]
Workup
X-Ray
- Delayed Bone Age

Hypertrophy
- Ventricular Hypertrophy
Ventricular hypertrophy is clinically differentiated into left and right ventricular hypertrophy. Short stature MedGen UID: 87607 •Concept ID: C0349588 • Finding A height below that which is expected according to age and gender norms. [ncbi.nlm.nih.gov]
Treatment
Treatment of manifestations: Surgical correction of the abnormal joints is the only treatment modality; however, surgical correction is often only partially successful and multiple procedures are needed. Physical therapy has not been effective. [ncbi.nlm.nih.gov]
Prevention
It is thus a chronic loss of joint motion due to structural changes in muscle, tendons, ligaments, or skin that prevents normal movement of joints. [ncbi.nlm.nih.gov]
