Arina Puzriakova Phenotypes for gene: DPM1 were changed from congenital muscular dystrophies; Congenital disorder of glycosylation, type Ie 608799 to Congenital disorder of glycosylation, type Ie, OMIM:608799
Zornitza Stark reviewed gene: DPM1: Rating: GREEN; Mode of pathogenicity: None; Publications: 23856421, 16641202, 10642602, 10642597; Phenotypes: Congenital disorder of glycosylation, type Ie 608799; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal; Current diagnostic: yes
Louise Daugherty commented on gene: DPM1: Only one case reported with variants in this gene and CMD, not sure it fulfils the criteria to be a green gene. Provisional rated Amber pending further cases or expert opinion.
Louise Daugherty Publications for gene: DPM1 were set to 23856421 - an infant with the phenotype of a congenital muscular dystrophy, with borderline microcephaly, hypotonia, camptodactyly, severe motor delay, and elevated creatine kinase. Muscle biopsy showed muscular dystrophy and reduced α-dystroglycan immunostaining with glycoepitope-specific antibodies in a pattern diagnostic of dystroglycanopathy. The infant was compound heterozygous for a novel missense variant and an intragenic deletion from exons 3-7. In vitro studies showed decreased DPM1 activity in fibroblasts, and reduced binding to DPM3; 23109149 - DPM2-CDG links the congenital disorders of glycosylation to the congenital muscular dystrophies
