Widening the phenotypic spectrum caused by pathogenic PDX1 variants in individuals with neonatal diabetes

BMJ Open Diabetes Res CarePublished Case series

Authors' conclusion

Our findings show that recessive PDX1 variants can cause a syndromic form of NDM, highlighting the need for clinical assessment of extrapancreatic features in individuals with NDM caused by PDX1 variants.
