Polydactyly is one of the most co mmon congenital limb dysplasia frequently observed in fa rm anima ls and varies e xpressivity. He rein, a preliminary investigation on inheritance types polydactylyin hundred four (104) ducklings produced by seven (7) mating g roups (MGs) different genotypes werereported. These were from non descript random bred population Muscovy ducks Netherlands data generat...

EDITOR—Nijmegen breakage syndrome (NBS) (OMIM 251260) is a rare autosomal recessive condition. The major manifestations include microcephaly, a distinct facial appearance, growth retardation, recurring infections owing to combined immunodeficiency, spontaneous chromosomal instability (with characteristic rearrangements of chromosomes 7 and 14), hypersensitivity to ionising radiation, and a very...

Polydactyly is perhaps one of the most common congenital hand and foot anomalies. Tetrapolydactyly (polydactyly 24) is a very rare form of hand and foot anomalies. Postaxial ray polydactyly usually occurs in male blacks without associated congenital abnormalities. We report a case of postaxial ray tetrapolydactyly in a female neonate which occurred sporadically and without associated congenital...

  This case report presents a case of Fanconi’s Anemia with an unusual thumb polydactyly in a 2-year old boy. The extra thumb had no nail, nail bed and distal phalanx. The extra thumb had no active motion.The duplication of the thumb occurred at the carpometacarpal joint but its morphology did not match with any classification described for thumb polydactyly. Although his thumb polydactyly was ...

Neonatal hydrometrocolpos (HMC) is a rare Mullerian duct anomaly with an incidence of 0.006%. It occurs due to blockage of the vagina with accumulation of mucus secretions proximal to the obstacle. These secretions are secondary to intrauterine and postnatal stimulation of uterine and cervical glands by maternal estrogens. A triad of congenital HMC, polydactyly, and cardiac anomalies are the ca...

Wing buds whose posterior half is excised, develop into wings lacking distal structures. However, such experimentally generated preaxial half wing buds can be rescued by implanting a retinoic-acid-releasing bead at their anterior margin. The polarity of the pattern that originates from preaxial half wing buds is reversed. For example, instead of a 234 digit pattern typical for normal wings, the...
