OBJECTIVE To delineate the phenotypic and molecular spectrum of patients with a syndromic variant of severe congenital neutropenia (SCN) due to mutations in the gene encoding glucose-6-phosphatase catalytic subunit 3 (G6PC3). STUDY DESIGN Patients with syndromic SCN were characterized for associated malformations and referred to us for G6PC3 mutational(More)
WHIM syndrome is an autosomal dominant immunodeficiency disease caused by mutations affecting the carboxy-terminus of CXCR4. To characterize novel genetic causes of the syndrome, we recruited a pediatric patient with possible WHIM syndrome, performed CXCR4 gene sequencing and compared his clinical phenotype and CXCR4 tail amino acid sequences with other(More)
