Systematic reassessment of reported variants in individuals with suspicion of Alport spectrum disorder reveals a high rate of ambiguous results.
"Alport spectrum disorder" describes a phenotypically and genotypically multifaceted disease entity encompassing classic autosomal recessive and X-linked Alport syndrome (AS) but also more heterogenous and typically milder, yet not benign, hematuric phenotypes like autosomal dominant AS, formerly also known as thin basement membrane nephropathy (TBMN). Alport spectrum disorder is associated with disease-causing variants in the type IV collagen genes COL4A3, COL4A4 and COL4A5. Variants and genotypes, reported by a genetic diagnostics lab between 2009 and 2014, of 91 index cases with the clinical tentative diagnosis of AS (66/91), TBMN (21/91), or AS/TBMN (not specified further; 4/91), were reassessed based on 2015 ACMG (American College of Medical Genetics and Genomics) criteria and current amendments. 80 different variants, all originally reported as "mutations", and their genotypes have been reassessed (COL4A3: 21/80, COL4A4: 15/80, COL4A5: 44/80). In 10/80 variants, classification changed from disease-causing to variant of uncertain significance (VUS). 69/91 (76%) index cases included in the analysis could be classified as solved. 22/91 (24%) index cases had an ambiguous result either on variant, genotype, or both variant and genotype level. VUS cases had a significantly more limited phenotype (e.g., isolated microscopic hematuria) compared to non-downgraded cases (e.g., additional extrarenal manifestations). Reassessment of variants/genotypes in this study showed a significant reduction in unequivocal genetic diagnoses highlighting variant and genotype interpretation as a dynamic process. Genetic reports of individuals with suspected Alport spectrum disorder, especially those obtained in the pre-ACMG criteria era, should therefore be critically evaluated.
Heterozygous X-linked Alport syndrome in a pregnant woman: A case report.
Alport syndrome is a genetic disorder of chronic kidney disease, hearing loss, and ocular abnormalities, caused by mutations in type IV collagen. While X-linked Alport Syndrome demonstrates characteristic severe renal failure in males, it has a variable presentation in females. Here, we present a case of a pregnant woman who was found to have X-linked Alport Syndrome with a heterozygous c.3587G>A (p.Gly1196Glu) mutation in the COL4A5 gene. The patient presented in her third trimester of pregnancy with preexisting chronic proteinuria. Family history was notable for kidney failure in her mother and two brothers, consistent with suspected hereditary nephropathy. She developed worsening proteinuria and new-onset hematuria, without preeclampsia or renal failure, and was induced at 39 weeks with an uncomplicated delivery. Genetic testing revealed a heterozygous c.3587G>A (p.Gly1196Glu) mutation in the COL4A5 gene, consistent with X-linked Alport Syndrome. Postpartum, the patient had mildly worsened proteinuria that transiently reached nephrotic range before improving, with normal to low blood pressures. Out of concern for symptomatic hypotension, she was not a candidate for first-line therapy with renin-angiotensin-aldosterone system blockade. In cases of hereditary nephropathies such as X-linked Alport Syndrome, cascade testing may be highly considered to identify family members at risk. Our case demonstrates the variable phenotype of X-linked Alport Syndrome in females and the need for close management during pregnancy, along with the benefits of early genetic testing, given the risks of long-term renal, hearing, and ocular manifestations of this disease.
The Inheritance Puzzle: A Case of Dual Genetic Kidney Disease.
Autosomal Dominant Polycystic Kidney Disease (ADPKD) and X-Linked Alport Syndrome (AS) are the most common monogenic causes of chronic kidney disease (CKD), each capable of independently leading to end-stage kidney disease (ESKD). However, the concurrent presence of both disorders in a single individual is exceedingly rare and poses significant diagnostic complexity. We report a unique case involving dual diagnosis of ADPKD and AS, attributed to a paternal PKD1 variant and a maternally inherited COL4A5 variant. Initial genetic testing through next-generation sequencing (NGS) identified PKD1 and COL4A5 variants in the Proband. While Sanger sequencing confirmed the PKD1 variant in the father, Sanger analysis of the Mother did not detect the COL4A5 variant despite her clinical signs, including persistent microhematuria and basement membrane abnormalities on electron microscopy. Further investigation using high-sensitivity approaches, like customised amplicon-based deep sequencing, confirmed low-level mosaicism for the COL4A5 variant in the Mother. This case underscores the critical role of advanced genetic testing in resolving atypical or dual presentations of kidney disease and highlights the need to consider mosaicism in unexplained inheritance patterns. Comprehensive family evaluation and precision diagnostics are essential for accurate counselling and management in such complex cases. This report contributes to the expanding spectrum of dual monogenic kidney disease.
Hereditary Myopathy With Early Respiratory Failure Associated With an Incidental COL4A5 Variant: A Case Report.
Hereditary myopathy with early respiratory failure (HMERF) is a rare autosomal dominant disorder caused by TTN variants. COL4A5 mutations are linked to X-linked Alport syndrome. A 34-year-old male developed progressive lower limb weakness, gait disturbance, nocturnal hypoventilation, and calf hypertrophy. Family history revealed similar symptoms in his mother and sister. Examination showed absent reflexes; MRI demonstrated muscle atrophy and fatty replacement; needle electromyography (EMG) was performed and showed findings consistent with advanced myopathy; however, it was not used as a primary diagnostic tool. Whole-exome sequencing identified a pathogenic TTN variant (c.95126C > G, p.Pro31709Arg), confirming HMERF. A hemizygous COL4A5 variant (c.4891C > T, p.Arg1631Cys) was also detected but lacked clinical correlation. This case illustrates a classic HMERF phenotype confirmed genetically, with an incidental COL4A5 variant of uncertain significance. It underscores the importance of genomic testing in atypical neuromuscular presentations and the need for cautious interpretation of incidental findings.
mRNA Therapy for Alport Syndrome.
Alport syndrome is caused by mutations in the type IV collagen genes COL4A3, COL4A4, and COL4A5 which are expressed in podocytes in the glomerulus of the kidney. Mutation of these genes disrupts blood filtration by the kidney leading to proteinuria and kidney failure. There is no cure for Alport Syndrome. Current therapies do not treat the genetic cause of the disease, but instead aim to delay the disease by reducing blood pressure in the kidney. Here we tested the ability of mRNA therapy to treat the disease. Mice with X-linked Alport syndrome (XLAS) due to mutation of Col4A5 were treated intravenously with lipid nanoparticles (LNPs) carrying three mRNAs encoding COL4A3, COL4A4, and COL4A5 to produce trimeric collagen IV repair proteins. This intravenous mRNA therapy significantly reduced proteinuria and blood urea nitrogen. Protection against the syndrome was maintained provided that LNP-mRNA injections were continued. However, efficacy was lost when therapy was terminated. These data provide proof of principle to apply a genetic mRNA therapy to halt progression of Alport syndrome in a mouse model of XLAS. These data also demonstrate that damage to the kidney filtration barrier can be leveraged to deliver large molecular therapies to podocytes and other cells within the kidney to treat Alport syndrome and other kidney genetic diseases.
