Genes affected

SHOX2 (HGNC:10854): (SHOX homeobox 2) This gene 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 genes have been characterized extensively as transcriptional regulators involved in pattern formation in both invertebrate and vertebrate species. 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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2009]

Collection Method: clinical testing

The c.407T>G (p.F136C) alteration is located in exon 2 (coding exon 2) of the SHOX2 gene. This alteration results from a T to G substitution at nucleotide position 407, causing the phenylalanine (F) at amino acid position 136 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
