Patient 3 is a 9-year-old female, born to third degree consanguineous parents at term by cesarean section for breech presentation. Birth weight was 3.25 kg (normal). She cried immediately after birth. She was referred for evaluation in view of bilateral dislocation of hip and knee joints and bilateral clubfeet. She has undergone multiple corrective orthopedic surgeries for club feet and hip dislocation. She started walking at 1 year and spoke simple sentences at 2 years.\nAt 2 years and 2 months, her height was 90 cm, OFC 48.5 cm and weight 11 kg (all are normal for age). She had prominent forehead, depressed nasal bridge, and telecanthus (Fig. ). She had spatulate thumbs, broad fingertips (Fig. ), and joint laxity. Joint laxity was noted in both knee joints (Fig. ), bilateral club feet and broad great toes were also noted (Fig. ). Bilateral elbow and wrist joints were normal. Skin, hair, and nails were normal. At 9 years of age, there was no evidence of hearing defect or compressive myelopathy. She is presently in 3rd grade and is good at studies.\nRadiographs revealed cervical kyphosis, subluxation at C3-C4 (Fig. ), and failure of fusion of posterior elements of cervical spine with mild scoliosis (Fig. ). Accessory calcaneal ossification (Fig. ) and clubfeet with metatarsus adductus (Fig. ) were also noted. Advanced carpal ossification was seen in radiographs at 22 months (Fig. ) of age though carpal ossification was age appropriate at 4 years and 7 months (Fig. ). She had normal right hip joint but increased medial joint space on left hip joint (Fig. ). Echocardiography was normal. Her complete blood counts, serum calcium, serum phosphorous, alkaline phosphatase, thyroid profile, and complete urine analysis were unremarkable.
Patient 1 is a 10-year-old boy. He was born to non-consanguineous parents at term by cesarean section. Birth weight was 3.25 kg (normal). He cried immediately after birth. He was referred for evaluation with bilateral club feet and cleft palate noted at birth and hyper-extensibility of both knee joints noted since 4 months of age. He was operated for cleft palate at 15 months of age. He has undergone multiple corrective orthopedic surgeries for clubfeet. He had recurrent lower respiratory tract infections until 2 years of age and he was found to have significant gastroesophageal reflux and was medically treated.

He had bilateral 5th finger clinodactyly, spatulate thumbs, broad fingertips, abnormal palmar creases and joint laxity (Fig. ). Hip and wrist joints were normal. Skin, hair, nails and teeth were normal. There was no evidence of hearing defect or compressive myelopathy. Other examinations were unremarkable, such as echocardiography and ophthalmology. At present, he is class four student and is average in studies.\nSkull radiography revealed normal cervical spine (Fig. ). Radiographs were suggestive of supernumerary carpal bones, short metacarpals (Fig. ), normal thoracolumbar spine (Fig. ), bilateral elbow joints dislocation (Fig. ) and cervical-dorsal scoliosis (Fig. ). Radiograph of pelvis with both hips was unremarkable (Fig. ). His complete blood count, serum calcium, serum phosphorous, alkaline phosphatase levels and complete urine analysis were unremarkable.
