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
Zornitza Stark (Australian Genomics), 7 Jul 2020"

PMID: 30290151, many of the affected patients also have hearing loss and the authors suggest that the Saul-Wilson syndrome variant is gain of function. Therefore, this gene should be considered to be Green at the next review.
