Inactivating G a variants lead to Albright s hereditary osteodystrophy (AHO) in the heterozygote, snggesting that G a haploinsnfficiency canses the disorder. AHO is characterized by short statnre, obesity, brachydactyly (shortening of metacarpal and metatarsal bones), snbcntaneous ossifications, and mental or developmental deficits (86,87). The severity of the phenotype is variable. Some patients with G a mutations have few or no symptoms. 

The scent marking of male feral boar, Sus scrofa, with metacarpal and preputial glands varies with rank and the social environment. The dominant boar marked more often than the subordinate one when paired, but did not mark at all when alone (Mayer and Brisbin, 1986). 

There is no information on in utero developmental effects in humans exposed to HCB, but oral exposure of young children has caused small or atrophied hands, short stature, pinched facies, osteoporosis of the carpal, metacarpal, and phalangeal bones, and painless arthritic changes. HCB has been demonstrated to cross the placenta in humans and in rodents. HCB residues have been detected in human milk and adipose tissue and in the blood of the umbilical cord of newborn infants and their mothers. Teratogenic effects were not...

Remove right forelimb (clavicle remains with axial skeleton), and examine scapula including tuberositas delteoidea, humerus, radius, ulna, metacarpals, and phalanges from all aspects. 

Even if there is little evidence that maternal toxicity (defined as reductions in maternal body weight) is consistently associated with major malformations, there is clear evidence that substantial reduction in maternal weight is linked with other manifestations of developmental toxicity. These manifestations include decreased fetal weights, and skeletal anomalies (e.g., wavy ribs) in rats and decreased fetal weights, post implantation loss, abortions, and skeletal defects in rabbits (e.g., unossified sternebrae, metatarsals, metacarpals, or caudal vertebrae).

In the first study, the patients had radiography of the left hand for bone age determination, and 12 had deferoxamine-induced long bone dysplasia (107). There was irregularity at the physeal-metaphyseal junction of the distal ulna (the site most frequently affected) and radius metaphyseal sclerosis was also common, especially of the ulna, but also of the radius, metacarpals, and phalanges. Radiolucent lesions occasionally accompanied metaphyseal sclerosis. In six patients with relatively mild lesions, the dysplastic changes had been missed or not mentioned.

Pituitary resistance to thyroid hormone (PRTH) refers to selective resistance of the pituitary thyrotrophs to thyroid hormone. About twice as many women as men have been reported with this rare, probably familial syndrome. Multiple abnormalities have been reported in the initial 50 reported cases including schizophrenia (three patients), mental retardation (two patients), short fourth metacarpals (one patient), and Marfanoid habitus (one patient). About 90% of patients studied have an appropriate increase in TSH in response to TRH conversely, the TSH will be suppressed by T3 administration.
