A Novel Pathogenic HSPG2 Mutation in Schwartz–Jampel Syndrome

Identification of a Novel Mutation in CNNM4 Gene in an Iranian Family with Jalili Syndrome

Background and Objectives: Jalili syndrome is a rare autosomal recessive genetic disorder, which so far, only 33 families with this disorder have been reported worldwide. Patients with this disease simultaneously develop cone-rod retinal dystrophy (CRD) and amelogenesis imperfecta (AI). In this study, a mutation causing Jalili syndrome, was investigated in an Iranian family.   Case Report: The...

Identification of a Novel CLCNKB Mutation in an Iranian Family with Bartter Syndrome Type 3.

Bartter syndrome (BS) is a group of uncommon genetic disorders of reabsorption of salt in the cortical thick ascending limb (TAL) of the Henle's loop, typically distinguished by metabolic alkalosis, salt loss, hypokalemia, hyperreninemic hyperaldosteronism and normal blood pressure. Bartter syndrome type 3, recognized as a classic BS (CBS), occurs because of mutations in CLCNKB gene. We enroll...

A novel pathogenic MLH1 missense mutation, c.112A > C, p.Asn38His, in six families with Lynch syndrome

BACKGROUND An unclassified variant (UV) in exon 1 of the MLH1 gene, c.112A > C, p.Asn38His, was found in six families who meet diagnostic criteria for Lynch syndrome. The pathogenicity of this variant was unknown. We aim to elucidate the pathogenicity of this MLH1 variant in order to counsel these families adequately and to enable predictive testing in healthy at-risk relatives. METHODS We st...

Novel mutation in the SLC19A2 gene in Thiamine-responsive megaloblastic anemia (Rogers’ syndrome)

Introduction: The Thiamine Transporter gene SLC19A2 is the only gene known to be associated with TRMA.  This syndrome is a trial clinical characterized by megaloblastic anemia, nonautoimmune diabetes mellitus and sensory-neural hearing loss. Methods: Described here are three children from consanguineous Iranian families with thiamine – responsive megaloblastic anemia (TRMA) or Rogers' syndrome....
