Short-stature homeobox 2, also known as homeobox protein Og12X or paired-related homeobox protein SHOT, is a protein that in humans is encoded by the SHOX2gene.[5][6][7]
SHOX2 is a member of the homeobox family of genes that encode proteins containing a 60-amino acid residue motif that represents a DNA-binding domain. Homeobox proteins have been characterized extensively as transcriptional regulators involved in pattern formation in both invertebrate and vertebrate species.[5]
Several human genetic disorders are caused by aberrations in human homeobox genes. This locus represents a pseudoautosomal homeobox gene that is thought to be responsible for idiopathic short stature, and it is implicated in the short stature phenotype of Turner syndrome patients. This gene is considered to be a candidate gene for Cornelia de Lange syndrome.[5]
SHOX2 localises on chromosome 3, so it is an autosomal and not a pseudoautosomal homeobox (SHOX, which localises on the PAR1 region of chromosome X and Y, has a pseudoautosomal hereditability).

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
