Elena Savva gene: STT3A was added gene: STT3A was added to Growth failure. Sources: Literature Mode of inheritance for gene: STT3A was set to BOTH monoallelic and biallelic, autosomal or pseudoautosomal Publications for gene: STT3A were set to PMID: 34653363; 23842455; 30701557; 28424003 Phenotypes for gene: STT3A were set to Congenital disorder of glycosylation, type Iw MIM#615596 Mode of pathogenicity for gene: STT3A was set to Other Review for gene: STT3A was set to GREEN Added comment: ID/DD reported in all cases (at least 7 individuals from 3 unrelated families, with 2 different homozygous variants in STT3A) PMID: 34653363 - 16 patients from 9 families with new AD mode of inheritance (both de novo and inherited). All variants were missense within/around acritical active/catalytic sites. Patients aged 3-55yo, with children noted to be "healthy" until reaching young adulthood Clinical features include dysmorphic features, macrocephaly (6/16), mild-moderate ID/DD (10/16), short stature (8/16), skeletal abnormalities (10/16), muscle cramps (7/16). Functional studies verifies AR disease is caused by LOF variants, whereas the AD variants cause DN proven by cotransfection in WT yeast resulting in impaired glycosylation (protein levels unchanged).
