Presentation

Cleft palate may be present. Radiographs reveal under-mineralisation and over-tubulation of the long bones, a bifid calcaneus and advanced bone age in the carpal, or extra carpal bones. [cags.org.ae]

The biliary disease presents itself in the form of choledochal cysts. Complicated/severe cases present with cholangitis or cholelithiasis which leads to sepsis. [lecturio.com]

CASE 123 Clinical Presentation A newborn infant presents with multiple dislocations of small and large joints, mild bowing of femora, bilateral clubfeet, and respiratory distress. [radiologykey.com]

While arthrogryposis means “stiff joints” and presents with the absence of muscles, or ones that are stiff and weak, Larsen Syndrome has dislocated joints and the muscles are present. [davidsfeldmanmd.com]

    Note moderate short stature, flat facial profile (fetal face–like appearance), short forearms, and small hands. [emedicine.medscape.com]

    The disorder is usually evident at birth, with short stature and multiple joint dislocations or subluxations that dominate the neonatal clinical and radiographic picture. [genecards.org]

  • Disability

    Symptoms can include pain in the lower back, hip/pelvic region, and proximal leg, as well as weakness/numbness above and below the knees. 59 However, in most patients, the dural ectasia is asymptomatic. 60 FIGURE 9 Dural ectasia of the lumbar spinal canal [pediatrics.aappublications.org]

    Severe disease with early onset may result in blindness in infants but milder disease may be asymptomatic even as adults. Cataracts may result. [disorders.eyes.arizona.edu]

    As a result, one or more of the parent’s children may inherit the germ cell gene FLNB mutation, leading to the development of Larsen syndrome, while the parent does not appear to have this disorder (asymptomatic carrier). [rarediseases.org]
