Prop1 Gene

Application of genetic analysis in clinical practice enables identifying a combination of two rare diseases in one patient. We report two cases of patients with hypopituitarism due to PROP1 gene mutations in combination with the 47,XYY karyotype (case 1) and autosomal dominant partial atrioventricular septal defect (case 2). These clinical cases clearly demonstrate that several rare diseases can be present in one patient. The morphology of the pituitary gland has specific features in patients with a PROP1 gene mutation: signal inversion on T1- and T2-weighted images, as well as changes in size of the pituitary gland over time. In case of short stature, the hormonal evidence of secondary hypopituitarism, low IGF-1 levels, and specific morphological features observed in MRI images, we recommended carrying out molecular genetic analysis of the PROP1 gene without conducting growth hormone stimulation test.

Abstract Background: Autosomal dominant polycystic kidney disease (ADPKD), the predominant type of inherited kidney disorder, occurs due to PKD1 and PKD2 gene mutations. ADPKD diagnosis is made primarily by kidney imaging. However, molecular genetic analysis is required to confirm the diagnosis. It is critical to perform a molecular genetic analysis when the imaging diagnosis is uncertain, particularly in simplex cases (i.e., a single occurrence in a family), in people with remarkably mild symptoms, or in individuals with atypical presentations. The main aim of this study is to determine the frequency of PKD1 gene mutations in Iranian patients with ADPKD diagnosis. Methods: Genomic DNA was extracted from blood samples from 22 ADPKD patients, who were referred to the Qaem Hospital in Mashhad, Iran. By using appropriate primers, 16 end exons of PKD1 gene that are regional hotspots, were replicated with PCR. Then, PCR products were subjected to DNA directional Sanger sequencing. Results: The DNA sequencing in the patients has shown that exons 35, 36 and 37 were non- polymorphic, and that most mutations had occurred in exons 44 and 45. In two patients, an exon-intron boundary mutation had occurred in intron 44. Most of the variants were missense and non-synonymous types. Conclusion: In the present study, we have shown the occurrence of nine novel missense or synonymous variants in PKD1 gene. These data could contribute to an improved diagnostic and genetic counseling in clinical settings.

Abstract Background: Autosomal dominant polycystic kidney disease (ADPKD) is the predominant type of inherited kidney disorder, which occurs due to PKD1 and PKD2 gene mutations. ADPKD diagnosis is made primarily by kidney imaging; however, molecular genetic analysis needs to be implicated to confirm the diagnosis. It is critical to perform a molecular genetic analysis when the diagnosis is uncertain, particularly in simplex cases (i.e., a single occurrence in a family), in people with remarkably mild symptoms, or in individuals with atypical presentations. The main aim of this study is to determine the likelihood of PKD1 gene mutations in Iranian patients with ADPKD diagnosis. Methods: Genomic DNA was isolated from blood samples from 26 ADPKD patients, who were referred to the Qaem Hospital in Mashhad, Iran. By using suitable primers, 16 end exons of PKD1 gene that are regional hotspots, were replicated with PCR. Then, PCR products were subjected to DNA directional Sanger sequencing.Results: The results of DNA sequencing in the patients showed that exons 35, 36 and 37 were non- polymorphic, while most mutations had occurred in exons 44 and 45. Only in two patients, exon-intron boundary mutation had occurred in intron 44. Most of the variants were missense and non-synonymous types. Conclusion: In this study, we present nine novel mutations/polymorphisms in PKD1. These data will contribute to an improved diagnostic and genetic counseling in clinical settings.
