Homozygosity for Proopiomelanocortin (POMC) Mutation in a Palestininan Child

Abu-Libdeh Abdulsalam , Abu-Libdeh Bassam

Background: Congenital Proopiomelanocortin deficiency (POMC) is a rare autosomal recessive disorder characterized by the association of adrenal insufficiency, early onset obesity, hyperphagia and altered skin & hair pigmentation. POMC is a complex propeptide encoding a range of melanocortin peptides that are released by tissue-specific proteolytic processing. These peptides have important roles in a range of functions such as skin pigmentation and the cont...

The N309K Pro-Protein Convertase Type 1 (PCSK1) Gene Mutation Causes Lack of Spontaneous Puberty and Primary Amenorrhea

Abdulhag Ulla Najwa , Sharaf Mona , Libdeh Abdulsalam Abu , Zangen David

Introduction: PCSK1/3 gene mutations are known as a cause for congenital diarrhea and various endocrinopathies. Hypogonadotrophic hypogonadism and aberrant pubertal development due to pro-convertase dysfunction was not characterized yet. This study aimed to characterize the pubertal development in a family carrying the novel N309K mutation in the PCSK1 gene.Methods and Results: We Identified 2 siblings who presented with severe congenital diarrhea follow...

Background: SGA is defined as birth weight under 2 standard deviations (SD) from the mean. Previous studies indicate that 10% of SGA babies do not have “catch-up growth” (CUG). They are eligible for growth hormone (GH) therapy to increase final height. The unexpected low demand for GH therapy in SGA babies, triggered us to survey the actual incidence of SGA and failure in CUG.Objective and hypotheses: To find the actual incidence of SGA and fai...
