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.

Genetic testing in recurrent pregnancy loss: when and which

Of all the clinically recognized pregnancies, about 15% end in a miscarriage, making this event one of the most common adverse events. Unfortunately, about 2-5% of couples take on recurrent pregnancy loss (RPL). However, “Recurrent pregnancy loss” definition, which according to the European Society of Human Reproduction and Embryology is the presence of two or […]

Sequencing machines: Roche 454

The first NGS platform Talking about the system of the Roche 454 means starting from the dawn of Next Generation Sequencing. The first three Next Generation Sequencing (NGS) platforms were produced by three independent companies which, a little later, were acquired by other industrial groups. System 454 is based on pyrosequencing, a technique based on […]

Genomic imprinting: 10 questions and 10 answers

An epigenetic event Genomic imprinting, although very studied, has many dark sides, even among healthcare professionals. Here are 10 frequently asked questions with relative answers on this phenomenon. 1. What is genomic imprinting? Genomic imprinting is an epigenetic process that modifies the DNA molecule without changing its nucleotide sequence. Regulator mechanisms of imprinting are not […]

Autosomal dominant inheritance

From parent to child Autosomal dominant inheritance happens when a genetic disorder is caused by a mutation in only one of the two copies of a gene (the paternal or the maternal one). In autosomal dominant inheritance, the disorder is transmitted from the parent to the offspring, but the parents can sometimes be clinically healthy […]

Mitochondrial genome

Only 37 genes Mitochondrial genome is contained in mitochondria, organelles responsible for cellular respiration. It is a small circular molecule present in a high number of copies. Mitochondrial genome has only 37 genes: 24 encode for transfer-RNA (tRNA) and ribosomal RNA (rRNA), while the other 13 genes are protein-coding. About 93% of mitochondrial DNA sequence […]

Mitochondrial inheritance

mtDNA mutations Genetic disorders with mitochondrial inheritance are those caused by mutations in the mitochondrial DNA. Mitochondrial DNA (often shorten to mtDNA) is contained in mitochondria, which are small organelles whose task is cellular respiration. An unknown number of chromosomes Mitochondrial DNA is made of many small circular double-stranded DNA molecules, called mitochondrial chromosomes (if […]

Inherited, genetic and congenital disorders

What’s the difference? Which is the difference between inherited, genetic and congenital disorders? We often hear about hereditary and/or genetic and/or congenital disorders. These terms are often confused or, even worse, used interchangeably. A hereditary disorder is certainly genetic: indeed it can be defined as a disease caused by a genetic mutation that has been […]

10 frequently asked question about mitochondrial inheritance

Here are some frequently asked questions (and their answers) about mitochondrial inheritance. For a general introduction to the topic you can read Mitochondrial Inheritance and Mitochondrial Genome. 1. Is mitochondrial DNA exclusively of maternal origin? Mitochondrial DNA is of almost exclusively maternal origin, even if a very little amount, clinically irrelevant and without any implication […]

Autosomal recessive inheritance

Two mutated alleles Autosomal recessive inheritance is defined as the manifestation of disease only when both the copies of a gene (maternal and paternal) are mutated. In other words, it is necessary that the final protein is quantitatively or qualitatively impaired in double dose. In autosomal recessive inheritance, parents are typically healthy carriers of a […]
