Congenital Disorders of Glycosylation v1.63 XYLT1_DBQD2_GGC Bryony Thompson STR: XYLT1_DBQD2_GGC was added
STR: XYLT1_DBQD2_GGC was added to Congenital Disorders of Glycosylation. Sources: Literature
Mode of inheritance for STR: XYLT1_DBQD2_GGC was set to BIALLELIC, autosomal or pseudoautosomal
Publications for STR: XYLT1_DBQD2_GGC were set to 30554721
Phenotypes for STR: XYLT1_DBQD2_GGC were set to Desbuquois dysplasia 2 MIM#615777
Review for STR: XYLT1_DBQD2_GGC was set to GREEN
STR: XYLT1_DBQD2_GGC was marked as clinically relevant
STR: XYLT1_DBQD2_GGC was marked as current diagnostic
Added comment: 10 patients from 8 families with homozygosity or compound heterozygosity for a (GGC)n repeat expansion in the XYLT1 promoter region, resulting in hypermethylation of XYLT1 exon 1. The GGC repeat region contains (GGC)n-AGC-(GGC)n-(GGA)n. Other loss of function variants in this gene also cause disease.
Normal: 9-20 GGC repeats
Pathogenic: 120-800 repeats
