PMID: 24931394 Stray-Pedersen et al 2014 - identified three unrelated children with recurrent infections, congenital leukopenia including neutropenia, B and T cell lymphopenia, and progression to bone marrow failure. Whole-exome sequencing demonstrated deleterious mutations in PGM3 in all three subjects, Two of the three children had skeletal anomalies resembling Desbuquois dysplasia: short stature, brachydactyly, dysmorphic facial features, and intellectual disability. However, these additional features were absent in the third child, showing the clinical variability of the disease.
PMID: 28543917 - Pacheco-Cuéllar et al 2017 - identified a novel homozygous mutation (c.1135T>C; p.Phe379Leu) in PGM3 in two siblings with bone marrow failure, severe combined immunodeficiency, renal and intestinal malformations, and a skeletal dysplasia resembling Desbuquois dysplasiaCreated: 7 May 2019, 10:20 p.m.
