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.

Inherited from the affected father in a male patient with personal and family history of dyschondrosteosis (PMID: 21912078); Observed in 2 unrelated patients referred for SHOX gene testing, however family studies showed the variant did not segregate with disease in one family (PMID: 23636926); In silico analysis suggests that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 21262861, 34426522, Sobieszczaska-Drodziel[CaseReport], 23636926, 21912078) -

Variant summary: SHOX c.86A>C (p.Lys29Thr) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00045 in 250928 control chromosomes, predominantly at a frequency of 0.00087 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 3.5 fold of the estimated maximal expected allele frequency for a pathogenic variant in SHOX causing Leri-Weill Dyschondrosteosis phenotype (0.00025). c.86A>C has been reported in the literature in at least an individual with clinical features of Leri-Weill dyschondrosteosis (example: SalmonMusial_2011). Family studies showed that the variant did not segregate with disease in one family (example: Bunyan_2013). At least one publication reports experimental evidence evaluating an impact on protein function on SHOX-SOX6 interaction (AzaCarmona_2014). The most pronounced variant effect results in about 80% of the WT clones on a Yeast two-hybrid system, which suggest this variant apparently did not affect SHOX-SOX6 interaction. The following publications have been ascertained in the context of this evaluation (PMID: 24421874, 21912078, 23636926). ClinVar contains an entry for this variant (Variation ID: 93095). Based on the evidence outlined above, the variant was classified as likely benign. -
