Abstract
Autosomal recessive polycystic kidney disease (ARPKD) is a rare but severe hereditary renal disorder characterized by bilaterally enlarged, cystic kidneys and varying degrees of hepatic fibrosis, often leading to early-onset kidney failure and significant morbidity. While most ARPKD cases are linked to mutations in the PKHD1 gene, recent advances in genomic sequencing have revealed that mutations in other genes, including PDIA6, may contribute to similar phenotypes. The PDIA6 gene encodes protein disulfide isomerase A6, which plays a critical role in protein folding within the endoplasmic reticulum (ER) and in the regulation of ER stress responses. Here, we report a rare and complex case of a full-term male neonate born to consanguineous Syrian refugee parents, who presented with a clinical constellation of features including polycystic kidney disease, severe oligohydramnios, pulmonary hypoplasia, microcephaly, rib thoracic dysplasia, and global developmental delay. Genetic analysis using whole-exome sequencing identified a homozygous two-base deletion in exon 5 of the PDIA6, resulting in a premature stop codon. Early diagnosis via genomic tools is essential for prognosis, management, and genetic counseling.
期刊介绍:
Clinical Genetics links research to the clinic, translating advances in our understanding of the molecular basis of genetic disease for the practising clinical geneticist. The journal publishes high quality research papers, short reports, reviews and mini-reviews that connect medical genetics research with clinical practice.
Topics of particular interest are:
• Linking genetic variations to disease
• Genome rearrangements and disease
• Epigenetics and disease
• The translation of genotype to phenotype
• Genetics of complex disease
• Management/intervention of genetic diseases
• Novel therapies for genetic diseases
• Developmental biology, as it relates to clinical genetics
• Social science research on the psychological and behavioural aspects of living with or being at risk of genetic disease
