Summary
Tuberous Sclerosis patients with large deletions involving the TSC2 and PKD1 genes may develop severe kidney disease. Genetic testing confirmed this contiguous gene syndrome in a young boy with early-onset renal cysts.
Area of Science:
- Genetics
- Molecular Biology
- Nephrology
Background:
- Tuberous Sclerosis is a genetic disorder caused by mutations in TSC1 or TSC2 genes.
- The TSC2 gene is located on chromosome 16p 13.3, near the gene for autosomal dominant polycystic kidney disease (PKD1).
- Large deletions can affect both TSC2 and PKD1, leading to TSC2/PKD1 contiguous gene syndrome.
Observation:
- A five-year-old boy with Tuberous Sclerosis presented with significant bilateral renal cysts detected neonatally.
- This clinical presentation suggested a potential contiguous gene deletion syndrome.
- The patient's condition indicated a poorer prognosis for renal complications.
Findings:
- Genetic analysis using the multiple ligation probe amplification (MLPA) technique was performed for confirmation.
- The study aimed to genetically confirm the TSC2/PKD1 contiguous gene syndrome in the reported case.
- Confirmation of the contiguous gene deletion syndrome was established.
Implications:
- TSC2/PKD1 contiguous gene syndrome necessitates careful renal monitoring in Tuberous Sclerosis patients.
- Early identification of this syndrome can guide prognosis and management strategies.
- Understanding these contiguous gene interactions is crucial for genetic counseling and therapeutic development.

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
01:12Loss of Tumor Suppressor Gene Functions
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
