Sandrow syndrome

Two patients with monomelic ulnar duplication with mirror hand polydactyly: segmental Laurin-Sandrow syndrome.

We have studied two unrelated boys with isolated left mirror hand and ulnar duplication. Neither had facial anomalies and family histories were unremarkable. We suggest that these boys have segmental Laurin-Sandrow syndrome, or mirror-image duplication, due to somatic mutation involving precursor cells of the left upper limb and that the facial and digital abnormalities in Laurin-Sandrow syndro...

Predicting the Future: Mirror Neurons Reflect the Intentions of Others

Microduplications encompassing the Sonic hedgehog limb enhancer ZRS are associated with Haas-type polysyndactyly and Laurin-Sandrow syndrome.

Laurin-Sandrow syndrome (LSS) is a rare autosomal dominant disorder characterized by polysyndactyly of hands and/or feet, mirror image duplication of the feet, nasal defects, and loss of identity between fibula and tibia. The genetic basis of LSS is currently unknown. LSS shows phenotypic overlap with Haas-type polysyndactyly (HTS) regarding the digital phenotype. Here we report on five unrelat...

Laurin-Sandrow syndrome (mirror hands and feet and nasal defects): description of a new case.

A child with complete syndactyly of cup shaped hands and mirror polysyndactyly of the feet, together with a nasal defect, was identified out of a total of 1,031,439 livebirths. She had a pattern of multiple congenital anomalies which was similar to that first described by Laurin et al in 1964 and by Sandrow et al in 1970. Two more cases with a similar pattern of congenital anomalies have recent...
