Genes affected

SHOX (HGNC:10853): (SHOX homeobox) This gene belongs to the paired homeobox family and is located in the pseudoautosomal region 1 (PAR1) of X and Y chromosomes. Defects in this gene are associated with idiopathic growth retardation and in the short stature phenotype of Turner syndrome patients. This gene is highly conserved across species from mammals to fish to flies. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.

Pathogenic, no assertion criteria provided	literature only	OMIM	Sep 01, 2004	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Genetics and Molecular Pathology, SA Pathology	Sep 08, 2020	The SHOX c.877T>C variant is a single nucleotide change from a thymine to a cytosine in exon 6 of the SHOX gene resulting in the abolition of the termination codon and an extension of the wild type protein by an additional 48 amino acids (PM4). The variant has been reported in a patient with Leri-Weill dyschondrosteosis and his similarly affected mother (PMID: 15356038) (PS4_supporting). The variant has been reported in dbSNP (rs137852559) but is absent from population databases (PM2). The SHOX gene is constraint for loss of function variants. The variant has not been reported in disease databases to date. The variant is paternally inherited. -
