We report on 44 patients (18 with additional affected family members), with congenital distal limb contractures identified from a large study of over 350 patients with congenital joint contractures. Fourteen propositi (seven familial cases, seven isolated cases) had a newly recognized form of arthrogryposis, which we have designated distal arthrogryposis type 1, with the predominant manifestations of autosomal dominant inheritance; tightly clenched fists at birth, with medially overlapping fingers, ulnar deviation, and camptodactyly in adults; and positional foot deformities. Contractures at other major joints are variable. There are no associated visceral anomalies; intelligence is normal. There can be marked intrafamilial and interfamilial variability. Twenty-two propositi with similar distal contractures had additional findings and were classified into five subcategories of distal arthrogryposis (type IIA-E). Among type II patients cleft palate, cleft lip, small tongue, trismus, ptosis, epicanthal folds, keratoconus, short stature, scoliosis, a unique hand position, and dull normal intelligence were seen. These characteristics were seen in various combinations and patterns and allowed sorting into groups that were the basis for the categorization. The remaining eight propositi were recognized to have previously described conditions with distal contractures and autosomal dominant inheritance, ie, the Freeman-Sheldon syndrome, trismus-pseudo-camptodactyly syndrome, congenital contractural arachnodactyly, and familial camptodactyly. Pathogenetically we postulate similar underlying defects of abnormal tendon attachments, attenuation, and absence; careful nosologic comparisons are important for prognostic counseling and habilitative management.

We report on two sibs, a girl, and a boy, with tall stature, long, and triangular faces, prominent foreheads with high frontal hairlines, telecanthus, downward slanting of the palpebral fissures, ptosis of the eyelids, everted lower eyelids, large ears, long noses, full, and everted vermilions, highly arched and narrow palates, tooth crowding, thin and long uvulae, coloboma of the alae, hyperextensible joints, long digits, positive thumb signs, flat feet, slightly diminished muscle strength, myopia, astigmatia, inguinal hernia, and vesical diverticula. Total body X-rays showed the presence of advanced bone age in both sibs and bilateral hallux valgus in the girl. Array-CGH did not reveal any pathological CNV. Molecular analysis of FBN1, FBN2, TGFBR1, TGFBR2, and CHST14 gene was normal, and SNP linkage analysis excluded more candidate genes. Differential diagnoses and the possibility that we might be reporting on a hitherto unreported syndrome are discussed.
