HIGH THROUGHPUT SEQUENCING IN GENETIC DISORDERS

By sequencing all human genes at once (whole exome and whole genome sequencing), genetic testing can be done in the blink of an eye. Based on the clinical information, we can look immediately at the most appropriate gene or panel or go straight to the interpretation of all data. For every clinical case, we have the right solution.

Breda Genetics deploys an articulated portfolio of tests, which comprises four different whole exome sequencing solutions (MENDEL FULL, EXOME 15MB, EXOME 60MB, EXOME 90MB), whole genome sequencing 30x (GENOME FULL), a list of hundreds of fully customizable exome or genome-based multigene panels (EXOME PANEL, GENOME PANEL), and a complete range of other forefront solutions and ancillary services, from exonic/multiexonic algorithmic CNV analysis based on NGS data (EXOME CNV, GENOME CNV), to family segregation studies, MLPA/qPCR and repeat expansion testing (SANGER CARRIER, SANGER GENE, MLPA/qPCR GENE, REPEAT PLUS).

The landscape of clinical genetics worldwide is often marked by widespread difficulty in accessing genetic counselling and genetic testing, either for geographical reasons, limited budgets or absence of equipped facilities. We make a point of giving access to medical genetics services to as many people as possible, offering acceptable turnaround times and fees. If you are unsure on whether you are in need of genetic testing, please request your genetic counseling now.

Arthrogryposis, distal, type 3 (DA3)

Summary DA3, or Gordon syndrome, is distinguished from other distal arthrogryposes by short stature and cleft palate. The syndrome is caused by mutationsin the PIEZO2 gene, which also causes DA5 (oculomelic amyoplasia) and Marden-Walker syndrome (MWKS). DA5 and MWKS are very similar to DA3 and are distinguished by ocular abnormalities and mental retardation, respectively (it […]

Arthrogryposis, distal, type 2B (DA2B)

Summary DA2B is thought to be the most common of the distal arthrogryposis disorders. Distal arthrogryposis is a clinically and genetically heterogeneous disorder characterized by clenched fist, overlapping fingers, camptodactyly, ulnar deviation, and positional foot deformities from birth. If distal arthrogryposis type 1 (DA1) is not associated with other abnormalities, other forms of DA such […]

Arthrogryposis, distal, type 2A (DA2A)

Summary Arthrogryposis, distal, type 2A (DA2A) is also known as Freeman-Sheldon syndrome (FSS) or whistling face syndrome and is caused by heterozygous mutation in the MYH3 gene. Mutations in this gene can also cause distal arthrogryposis type 2B (also known as Sheldon-Hall syndrome, a genetically heterogeneous subtype of distal arthrogryposis caused also by mutations in the […]

Arthrogryposis multiplex congenita, distal, type 1B (DA1B)

 Clinical summary Distal arthrogryposis type 1 (DA1) is characterized by multiple contractures of hands and feets (camptodactyly and clubfoot), no visceral organ involvement and normal intelligence. Large multigenerational families have been reported. DA1 type B (DA1B) is caused by mutation in the in the MYBPC1 gene (heterozygous mutations in this gene also cause DA type 2). The […]

Arthrogryposis multiplex congenita, distal, type 1A (DA1A)

Clinical summary Arthrogryposis multiplex congenita, distal, type 1 (DA1) is the prototypic form of distal arthrogryposis and as such is largely characterized by camptodactyly (permanently bent fingers and toes) and clubfoot (inward- and upward-turning foot). Recent evidence suggests that DA1A due to TPM2 mutations results from muscle dysfunction, although distal arthrogryposis was originally defined as being […]

Allan-Herndon-Dudley syndrome

Recommended panel testing at Breda Genetics for this condition: Allan-Herndon-Dudley syndrome and its differential diagnosis (ABCD1, ASPA, ARSA, GALC, GJC2, MECP2, PLP1, SLC16A2, SMS, THRA) Summary Allan-Herndon-Dudley syndrome (AHDS), also known as MCT8-specific thyroid hormone cell-membrane transporter deficiency, is a rare disorder of brain development with neuromuscular involvement accompanied by specific changes in circulating thyroid […]

Lysosomal acid lipase deficiency (Wolman disease and CESD)

Recommended panel testing at Breda Genetics for this condition: Lysosomal acid lipase deficiency (Wolman/CESD) and its differential diagnosis (LIPA, SMPD1, GBA, LDLR, APOB, PCSK9, LDLRAP1). Summary Lysosomal acid lipase deficiency is caused by homozygous or compound heterozygous mutation in the LIPA gene. Lysosomal acid lipase deficiency is predominantly a pediatric disease, although milder forms of […]

RNA extraction tips

A vulnerable molecule RNA extraction from biological samples is complicated by the vulnerability of the RNA molecule itself and by the ubiquitous presence of ribonuclease enzymes in cells, tissues, and environment which can rapidly degrade RNA (for instance, RNase 7, a member of the RNase A superfamily is secreted by human skin and serves as […]

GATK

GATK: the Genome Analysis Toolkit The Genome Analysis Toolkit or more simply, GATK, is a software which is widely used to analyze high throughput sequencing data. GATK has been developed by the Data Science and Data Engineering group working at the Broad Institute. This specialized toolkit provides users with a broad selection tools and to focus on variant discovery, genotyping and data quality […]
