Exploring the Clinical Implications of a LARS2 Gene Mutation in a Female Adolescent with Perrault Syndrome

Yang Tong , Ferreira Madalena , Sousa Filomena , Amorim Marta , Lopes Lurdes , Galhardo Júlia

Introduction: Perrault syndrome is a rare autosomal recessive (AR) disorder (<1:1.000.000). Mutations in several genes, including HSD17B4, HARS2, CLPP, LARS2, TWNK, and ERAL1 have been associated with it, reflecting the genetic and clinical heterogeneity of this condition. It is characterized by bilateral mild to severe sensorineural hearing loss (SNHL) in both sexes and gonadal dysgenesis in 46,XX karyotype females. Ovarian dysfunction ranges from underdev...

ABCC8 gene mutations: two mirror reflections

Ferreira Madalena , Yang Tong , Câmara Beatriz , Cabral Mafalda , Simões Anabela , Monteiro Arminda , Lopes Lurdes , Galhardo Júlia

Introduction: The ABCC8 gene encodes the SUR1 subunit of the ATP-sensitive potassium channel (K-ATP) in pancreatic beta cells, a key pathway in insulin secretion. Mutations in this gene are associated with neonatal diabetes (ND), and congenital hyperinsulinism (CHI).Description: Cases 1 and 2 Two male monozygotic twins, with no significant medical history, developed persistent non acidotic ketotic hyperg...
