Skeletal dysplasia v4.48 MGP Achchuthan Shanmugasundram Added comment: Comment on mode of inheritance: As there is sufficient evidence available (two unrelated cased and functional studies) for the association of monoallelic MGP variants with spondyloepiphyseal dysplasia, the MOI should be updated from 'BIALLELIC, autosomal or pseudoautosomal' to 'BOTH monoallelic and biallelic, autosomal or pseudoautosomal' in the next GMS review.
Skeletal dysplasia v4.48 MGP Achchuthan Shanmugasundram Mode of inheritance for gene: MGP was changed from BIALLELIC, autosomal or pseudoautosomal to BIALLELIC, autosomal or pseudoautosomal
Skeletal dysplasia v4.47 MGP Achchuthan Shanmugasundram Phenotypes for gene: MGP were changed from Keutel syndrome 245150; Keutel syndrome 245150 to Keutel syndrome, OMIM:245150; spondyloepiphyseal dysplasia, MONDO:0016761

Skeletal dysplasia v4.45 MGP Achchuthan Shanmugasundram Tag Q1_24_MOI tag was added to gene: MGP.
Skeletal dysplasia v4.45 MGP Achchuthan Shanmugasundram changed review comment from: PMID:37923733 reported four individuals from two unrelated families with two different heterozygous MGP variants affecting Cys 19 residue (family 1: p.Cys19Phe; family 2: p.Cys19Tyr) and with previously undescribed spondyloepiphyseal dysplasia characterized by short stature with a short trunk, diffuse platyspondyly, midface retrusion, progressive epiphyseal anomalies and brachytelephalangism. In addition, functional evidence from heterozygous ‘knock-in’ mice expressing Cys19Phe MGP recapitulate most of the skeletal anomalies observed in the affected individuals.; to: PMID:37923733 reported four individuals from two unrelated families with two different heterozygous MGP variants affecting Cys 19 residue (family 1: p.Cys19Phe; family 2: p.Cys19Tyr) and with previously undescribed spondyloepiphyseal dysplasia characterized by short stature with a short trunk, diffuse platyspondyly, midface retrusion, progressive epiphyseal anomalies and brachytelephalangism.

Although phenotype caused by biallelic MGP variants are already reported in both OMIM (MIM #245150) and Gene2Phenotype, phenotype caused by monoallelic variants are not yet reported in either resources.
