Acrocapitofemoral dysplasia (ACFD) is an autosomal recessive skeletal dysplasia characterized by postnatal-onset disproportionate short stature, relatively large head, narrow thorax, lumbar lordosis, short limbs, and brachydactyly with small broad nails (Ozyavuz Cubuk and Duz, 2021).

Shohat-type spondyloepimetaphyseal dysplasia (SEMDSH) is a chondrodysplasia characterized by vertebral, epiphyseal, and metaphyseal abnormalities, including scoliosis with vertebral compression fractures, flattened vertebral bodies, and hypomineralization of long bones. Affected individuals may exhibit a small trunk, short neck, small limbs, joint laxity, bowlegs, and/or abdominal distention with hepatosplenomegaly (summary by Egunsola et al., 2017).
