Independence of brachymesophalangia‐5 from brachymesophalangia‐5 with cone mid‐5
Analysis of hand radiographs of juvenile siblings of juvenile propositi indicates that brachymesophalangia‐5 alone (without cones) is separately inherited without apparent sex bias while brachymesophalangia‐5 with the cone‐epiphysis of mid‐5 and the cone‐epiphysis of mid‐5 alone are both apparently inherited as a complex and with a marked excess of females over males
Confirmation of the sex difference in continuing subperiosteal apposition
A major sex difference in the rate of continuing bone expansion was confirmed for 5660 adult subjects of European ancestry. The five‐decade gain in metacarpal midshaft area amounted to 8.4% in 3455 females and 2.8% in 2205 males. There was no systematic age effect on the length of the second metacarpal. Accordingly, both bone expansion and the marked sex difference in its magnitude may be attributed to sex‐specific aspects of ageing much like the…
Size reduction associated with brachymesophalangia‐5: A possible selective advantage
Subjects with brachymesophalangia‐5 (the short middle segment trait of the fifth digit) are systematically reduced in the length of the second metacarpal and in stature, by approximately 0.5 standard deviations, in contrast with unaffected individuals or unaffected siblings of affected propositi. There is conclusive evidence for axial and appendicular length reduction in affected individuals, and the smaller body size associated with brachymesoph…
Analysis of triquetral‐lunate fusion
Fusion of the centers of the triquetral and lunate (the os lunato‐triquetrum) was observed in 1.6% of 7,543 subjects primarily of African origin as compared with 0.1% of 11,663 persons of European origin. The fusion was twice as common in females as in males, multifactorial inheritance was suggested in the lineages studied, and a possible selective disadvantage was postulated after comparison with West African fusion frequencies
