Preaxial polydactyly of the foot
Background and purpose - Preaxial polydactyly of the foot is a rare malformation and clinicians are often unfamiliar with the associated malformations and syndromes. In order to give guidelines for diagnostics and referral to a clinical geneticist, we provide an overview of the presentation using a literature review and our own patient population. Patients and methods - The literature review wa...
متن کاملEvidence that preaxial polydactyly in the Doublefoot mutant is due to ectopic Indian Hedgehog signaling.
Patterning of the vertebrate limb along the anterior-posterior axis is controlled by the zone of polarizing activity (ZPA) located at the posterior limb margin. One of the vertebrate Hh family members, Shh, has been shown to be able to mediate the function of the ZPA. Several naturally occurring mouse mutations with the phenotype of preaxial polydactyly exhibit ectopic Shh expression at the ant...
متن کاملFurther evidence for preaxial hallucal polydactyly as a marker of diabetic embryopathy.
Maternal diabetes has an established aetiological link with developmental abnormalities, and the prevalence of major congenital malformations in the offspring of affected women is approximately 4-8%, compared to the general population risk of about 3%. Hallucal polydactyly, particularly with an unusual proximal placement of the extra digit, has been reported as a distinctive anomaly in diabetic...
متن کاملRare case of tibial hemimelia, preaxial polydactyly, and club foot
A seven-month old female presented with left tibial hemimelia (or congenital tibial aplasia; Weber type VIIb, Jones et al type 1a), seven-toed preaxial polydactyly, and severe club foot (congenital talipes equinovarus). Definitive amputation surgery disarticulated the lower limb at the knee. This case report describes the anatomical findings of a systematic post-amputation examination of the lo...
متن کاملAnother case of microcephaly, facial clefting, and preaxial polydactyly.
We describe a nine month old boy with failure to thrive, developmental delay, bilateral cleft lip and palate, and left preaxial polydactyly. The features are similar to those in a child described by Howard and Young and may be the second case of a previously unknown syndrome.
