Symphalangism-brachydactyly syndrome
Multiple synostoses syndrome is characterized by multiple joint fusions, usually commencing in the hands, conductive deafness, and characteristic facial features, including a broad, tubular-shaped nose and a thin upper vermilion. Other features include brachydactyly, hypoplastic or absent middle phalanges, radial head dislocation, and pectus carinatum (summary by Takahashi et al., 2001). Genetic Heterogeneity of Multiple Synostoses Syndrome Other forms of multiple synostoses syndrome include SYNS2 (610017), caused by mutation in the GDF5 gene (601146) on chromosome 20q11; SYNS3 (612961), caused by mutation in the FGF9 gene (600921) on chromosome 13q12; and SYNS4 (617898), caused by mutation in the GDF6 gene (601147) on chromosome 8q22.

Pelviscapular dysplasia
Syndrome with characteristics of pelviscapular dysplasia with epiphyseal abnormalities, congenital dwarfism and facial dysmorphism. The facial dysmorphism has manifestations of frontal bossing, hypertelorism, narrow palpebral fissures, deep-set eyes, strabismus, low-set posteriorly rotated and malformed ears, dysplasia of conchae, a small chin, a short neck with redundant skin folds, and a low hairline. Intelligence may vary from normal to moderately impaired. Radiographic features comprise aplasia of the body of the scapula, hypoplasia of the iliac bone, humeroradial synostosis, dislocation of the femoral heads, and moderate brachydactyly. Mutations in the TBX15 gene have been identified as potentially causative. Pelviscapular dysplasia is phenotypically similar to pelvis-shoulder dysplasia. [from SNOMEDCT_US]
Arthrogryposis, distal, IIa 11
Distal arthrogryposis type 11 (DA11) is an autosomal dominant disorder characterized mainly by camptodactyly. Other features include absent flexion creases and limited forearm supination (Zhou et al., 2019). [from OMIM]
ENDOVE syndrome, limb-only type
Limb-only ENDOVE syndrome (ENDOVESL) is characterized by marked mesomelic shortening and deformation of the lower limbs due to severe hypoplasia of the tibia and fibula. Patients also exhibit abnormalities of the digits of the hands and feet, with cutaneous and osseous syndactyly as well as dysplastic, missing, and/or volar nails. In addition, genitourinary anomalies have been observed (Allou et al., 2021). [from OMIM]
Absent proximal finger flexion creases
Absence of the proximal interphalangeal flexion creases of the fingers. [from HPO]
