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.

Variant summary: SHOX c.597C>T alters a non-conserved nucleotide resulting in a synonymous change. Consensus agreement among computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 4e-05 in 251160 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in SHOX causing Langer Mesomelic Dysplasia (4e-05 vs 0.0022), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.597C>T in individuals affected with Langer Mesomelic Dysplasia and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as likely benign. -
