Title: Molecular analysis and clinical findings of Griscelli syndrome patients. Author: Durmaz A, Ozkinay F, Onay H, Tombuloglu M, Atay A, Gursel O, Peker E, Atmaca M, Genel F, Bozabali S, Akin H, Ozkinay C. Journal: J Pediatr Hematol Oncol; 2012 Oct; 34(7):541-4. PubMed ID: 22983416. Abstract: Griscelli syndrome (GS) is a rare autosomal recessive disorder associated with skin or hair hypopigmentation, hepatosplenomegaly, pancytopenia, and immunologic and central nervous system abnormalities. GS type II is caused by RAB27A mutations. We present RAB27A mutation analysis of 6 cases diagnosed as GS type II. Missense mutations (L26P and L130P) in 2 cases, deletion of 5 bases (514delCAAGC) in 2 cases, and 1 base deletion (148delA) in 2 cases were detected. This report has importance in phenotype-genotype correlation of different types of mutations including missense mutations and deletions within the RAB27A gene in GSII syndrome.[Abstract] [Full Text] [Related] [New Search]
