Summary
Whole-exome sequencing successfully identified a HOXA13 mutation causing Hand-foot-genital syndrome. This case highlights the diagnostic power of whole-exome sequencing for Mendelian disorders.
Area of Science:
- Genetics
- Molecular Biology
- Genomic Medicine
Context:
- Monogenic and oligogenic diseases require advanced genetic analysis.
- Whole-exome sequencing (WES) is a key tool for diagnosing Mendelian disorders by targeting protein-coding genes.
- Identifying specific gene mutations is crucial for understanding disease mechanisms.
Purpose:
- To demonstrate the utility of whole-exome sequencing in diagnosing rare genetic disorders.
- To report a novel case of Hand-foot-genital syndrome caused by a specific HOXA13 mutation.
- To showcase successful application of WES in clinical genetic analysis.
Summary:
- Next-generation sequencing, specifically whole-exome sequencing (WES), was employed for genetic analysis.
- A case of Hand-foot-genital syndrome was diagnosed, attributed to a HOXA13 mutation (c.1102A>T, p.Ile368Phe).
- This finding represents a successful application of WES in identifying the genetic basis of a Mendelian disease.
Impact:
- This case underscores the effectiveness of WES in diagnosing complex genetic syndromes.
- The identification of the HOXA13 mutation provides valuable information for genetic counseling and potential therapeutic strategies.
- Successful WES analyses contribute to the growing knowledge base for rare genetic diseases.

2.3K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

01:33Pleiotropy
44.0K
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,...

01:43Sex-linked Disorders
110.7K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

10.0K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

16.6K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

6.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
