•Secondary skull deformity is often present due to the premature closure of cranial sutures. •Cloverleaf skull deformity is generally seen in type 2. • Polyhydramnios is present in almost 50% of cases. [slideshare.net]

Musculoskeletal
- Lordosis
Kyphosis and exaggeration of the normal lumbar lordosis are common. The proximal segments of the limbs are shorter than the hands and feet, which often appear normal. Some infants have clubfoot or exhibit hypotonia. [clinicalgate.com]
[…] type Disease definition Spondyloepimetaphyseal dysplasia, matrilin-3 type is characterized by disproportionate early-onset dwarfism, bowing of the lower limbs, short, wide and stocky long bones with severe epiphyseal and metaphyseal changes, lumbar lordosis [orpha.net]
Someone with SEMD, MATN3-related will have lordosis (swayback). This is a lower back that is too curved. SEMD, MATN3-related is passed down from parents to their children through genes. Genes act as an instruction manual for the body. [diseaseinfosearch.org]
Several other skeletal changes such as lumbar lordosis and flat vertebral bodies characterize the disease. [genome.jp]
Affected individuals presented with disproportionate early-onset dwarfism, bowing of the lower limbs, lumbar lordosis, and normal hands. [omim.org]

He had a waddling gait since he started walking (at 1 year), short limbs with severe short stature, bowing of lower limbs, and severe lumbar lordosis. At 13 years of age, he underwent bilateral osteotomy of both proximal tibiae for severe bowing. [jmg.bmj.com]
A: Patient 1 at the age of 2 years and 5 months, note the disproportionate short stature with short trunk and genu varum. [docslide.com.br]
Short stature is observed usually secondary to the pathologic bone and its deformities. There are several clinical forms of osteogenesis imperfecta, with different degree of severity. [intechopen.com]
- Disproportionate Dwarfism
Someone with SEMD, MATN3-related will have early-onset disproportionate dwarfism. This means that they will be shorter than most other people. They will also have body parts that are too large or small compared to their body size. [diseaseinfosearch.org]
All five affected individuals presented with disproportionate early-onset dwarfism, bowing of the lower limbs, lumbar lordosis, and normal hands. [jmg.bmj.com]
•Thanatophoric dysplasia is characterized by disproportionate dwarfism with very short extremities, which are bowed in type 1 and may be 66. •The trunk length is normal, but the thorax is narrow. [slideshare.net]
- Short Extremities
Note the short extremities, relatively normal hands, flat facies, and exaggerated lordosis. Skeletal radiographs of the newborn reveal short tubular bones, delayed ossification of vertebral bodies, and proximal limb bone epiphyses ( Fig. 686-3 ). [clinicalgate.com]
Is the thorax extremely small (thanatophoric dysplasia)? 2. Is the thorax long and narrow (Jeune syndrome)? 3. Are the ribs extremely short (short-rib polydactyly)? 4. Are fractures present (osteogenesis imperfecta type II)? 54. 5. [slideshare.net]
