Added comment: This gene is associated with a phenotype in OMIM and Gene2Phenotype. This gene was added to the Cataracts panel by Zornitza Stark (Australian Genomics).

"Saul-Wilson syndrome (AD): 14 patients reported with DD, skeletal changes, cataracts, and growth retardation (progeriod like) All have a recurrent de novo heterozygous missense variant (p.Gly516Arg). Please note bi-allelic variants cause CDG. Sources: Expert list

PMID: 30290151, many of the affected patients also have short stature and the authors suggest that the Saul-Wilson syndrome variant is gain of function. After consulting the Genomics England Clinical Team, it was suggested that this gene should be added to this panel for the short stature phenotype. However, the GMS specialist group should review whether the short stature is likely associated with the underlying skeletal findings.

Therefore, this gene has been given an Amber rating until further review from the GMS specialist group to see if the phenotype is appropriate for this panel.
