A Rare Consanguineous Case of Alazami Syndrome in a Jordanian Family: Clinical Presentation, Genetic Analysis, and Therapeutic Approaches - A Case Report

Objective: Alazami syndrome (AS) is an infrequent genetic disorder inherited in an autosomal recessive pattern, characterized by the presence of multiple congenital abnormalities. This study explores a case of a 4-year-old girl with AS, examining symptoms, genetic factors, and treatment ef?icacy. Case report: A 4-year-old girl, born to consanguineous Jordanian parents, displayed dysmorphic features including low birth weight, microcephaly, hyperthyroidism, short stature, blue sclera, triangular-shaped face, deep-set eyes, narrow palpebral ?issures, and a prominent forehead. Examination revealed height (92 cm) and weight (7.7 kg) below the 5th and 3rd percentiles respectively. Blood tests and renal ultrasound were normal. Whole exome sequencing (WES) identi?ied a homozygous eight-base pair deletion within exon 5 of the LARP7 gene on chromosome 4q25, con?irming the diagnosis of AS, an autosomal recessive disorder. This variant induces frameshift mutations leading to premature stop codons, suggesting a probable mechanism of illness via loss of function. Treatment involving growth monitoring and therapy led to signi?icant improvements in height, weight, and communication skills within three months. Conclusion: We describe a rare autosomal recessive AS case due to consanguinity, with a frameshift mutation in the LARP7 gene found via WES. Our AS treatment program effectively alleviates symptoms and enhances developmental progress.
