Helen Brittain (Genomics England Curator)

Comment when marking as ready: Laurin-Sandrow syndrome represents radial aplasia but with ulnar dimelia, therefore phenotype appropriate for inclusion. Note that reported cases with this phenotype have resulted from microduplications. Spectrum of other radial ray manifestations associated with variants in this gene. Therefore included.

Rebecca Foulger (Genomics England curator)

Laurin-Sandrow syndrome (LSS) is caused by heterozygous mutation in an SHH regulatory element (ZRS) that resides in intron 5 of the LMBR1 gene.
