UniProtKB/Swiss-Prot : ⁷⁶ Short stature, onychodysplasia, facial dysmorphism, and hypotrichosis: A syndrome characterized by severely short long bones, peculiar facies associated with paucity of hair, and nail anomalies. Growth retardation is evident on prenatal ultrasound as early as the second trimester of pregnancy, and affected individuals reach a final stature consistent with a height age of 6 years to 8 years. Relative macrocephaly is present during early childhood but head circumference is markedly low by adulthood. Psychomotor development is normal. Facial dysmorphism includes a long, triangular face with prominent nose and small ears, and affected individuals have an unusual high- pitched voice. Clinodactyly, brachydactyly, and hypoplastic distal phalanges and fingernails are present in association with postpubertal sparse and short hair. Typical skeletal findings include short and thick long bones with mild irregular metaphyseal changes, short femoral necks, and hypoplastic pelvis and sacrum. All long bones of the hand are short, with major delay of carpal ossification and cone- shaped epiphyses. Vertebral body ossification is also delayed.

MalaCards based summary : Short Stature, Onychodysplasia, Facial Dysmorphism, and Hypotrichosis, also known as soft syndrome, is related to alveolar soft part sarcoma and soft tissue sarcoma, and has symptoms including waddling gait An important gene associated with Short Stature, Onychodysplasia, Facial Dysmorphism, and Hypotrichosis is POC1A (POC1 Centriolar Protein A). Affiliated tissues include bone and eye, and related phenotypes are hypertelorism and diabetes mellitus

Relative macrocephaly is present during early childhood but head circumference is markedly low by adulthood. Psychomotor development is normal.

All long bones of the hand are short, with major delay of carpal ossification and cone-shaped epiphyses. Vertebral body ossification is also delayed (summary by Sarig et al., 2012). (614813)
