Laboratory at the YEARS clinic in Berlin — sequencing and genetic interpretation

Genetic analysis

Your genome is not a fate. It is a map.

Panel, array, exome, genome: four methods that measure very different things. What each delivers, what a finding actually triggers, and what German law requires. Physician-led, with counselling before and after the examination.

  • Exome and genome sequencing
  • 170+ curated risk genes
  • Genetic counselling under German law
  • Part of YEARS Ultimate

In brief

What a genetic analysis delivers, and what it does not

A genetic analysis reads your hereditary information and looks for variants with medical meaning. What matters is not the volume of data but the type of finding it produces. Monogenic findings with high penetrance such as BRCA1 or familial hypercholesterolaemia are covered by guidelines and trigger defined consequences. Pharmacogenetics demonstrably changes drug dosing. Polygenic risk scores shift a probability without establishing a diagnosis. Lifestyle genetics we do not treat as actionable. In Germany a predictive examination may only be ordered by a physician, with genetic counselling before and after the test.

The methods

Four ways to read a genome.

The methods differ not in accuracy but in how much they look at in the first place. Comparing an array with genome sequencing means comparing a sample with a full survey.

MethodWhat is readWhat can be foundAt YEARS
Gene panelA fixed selection of genes, usually 10 to 200Known disease-relevant variants in exactly those genesAs targeted follow-up where there is a specific suspicion
SNP arrayIndividual predefined positions, typically 500,000 to 1 millionCommon variants, the basis of polygenic risk scoresNot as a primary method — it only reads what was asked in advance
Whole exome sequencingAll protein-coding regions, around 1-2 % of the genomeThe majority of variants that are clinically interpretable todayStandard in the Ultimate analysis
Whole genome sequencingThe entire genome, coding and non-codingAdditionally structural variants and pharmacogenetics in full breadthStandard in the Ultimate analysis

More data does not automatically mean more insight. Genome sequencing reads roughly fifty times as many bases as the exome, but the share of that which can be interpreted with clinical confidence today is considerably smaller. The gain lies less in volume than in particular classes of finding: structural variants and complete pharmacogenetic interpretation.

Evidence

Not every finding carries the same weight.

This is the most important distinction in the field, and the one most often blurred in the marketing of genetic tests. We assign every type of finding to the evidence tier it actually sits on.

Tier 1

Guideline- and endpoint-based

BRCA1/2, Lynch syndrome, familial hypercholesterolaemia, haemochromatosis, pharmacogenetics (CYP2C19, DPYD, TPMT)

May justify a diagnosis, a treatment or a shorter screening interval. Written into medical guidelines.

Tier 2

Study-based, without guideline status

ApoE status, selected cardiometabolic variants, carrier status for recessive conditions

May justify observation and inform how other diagnostics are prioritised. Does not on its own trigger treatment.

Tier 3

Research-adjacent

Polygenic risk scores, lifestyle genetics such as COMT or MTHFR, epigenetic ageing models

Provides context, triggers no diagnosis and no treatment. Predictive performance outside European cohorts is poorly documented.

This classification is not a marketing statement but the system by which we assess and publicly declare every procedure in our programmes.

Legal framework

Why an online gene test is a different thing.

The German Genetic Diagnostics Act draws a clear line between a medical genetic examination and posting off a saliva sample. That line is not a bureaucratic detail, it is the difference between a finding a physician can work with and a file you are left to interpret yourself.

  • Predictive genetic examinations may only be ordered by a physician.
  • Genetic counselling is mandatory before and after the examination.
  • Consent is given in writing and can be withdrawn at any time.
  • You have a right not to know — individual findings can be excluded.
  • Employers and insurers may neither demand genetic examinations nor accept results.

At YEARS a physician conducts the pre-test consultation before the blood draw and the discussion of findings afterwards. Both are included in the programme and are not optional.

Process

From blood draw to plan.

Step 01

Consultation and family history

A medical conversation about the aim, reach and limits of the examination. We record family history across three generations, because it determines which findings are relevant at all.

Step 02

Blood draw and sequencing

One EDTA blood sample is enough, no saliva kit. Exome and genome sequencing in an accredited laboratory, with interpretation of more than 170 clinically curated risk genes.

Step 03

Discussion of findings

After four to six weeks, a personal consultation: which variants were found, which evidence tier they sit on, and what follows for screening intervals, medication and diagnostics.

Limits

What genetics cannot do.

We say this openly, because the alternative is a report that creates more expectation than it can meet.

  • Genetics says nothing about your current state. An unremarkable genome does not rule out an existing condition.
  • Most lifestyle diseases are polygenic and strongly environment-dependent. The genetic share explains part of the picture, not the outcome.
  • Variants of uncertain significance occur. They are named as such and not reinterpreted into a recommendation.
  • Blood pressure, ApoB, Lp(a), HbA1c and imaging say more about your next ten years than your genome does.

Frequently asked questions about genetic analysis

A genetic analysis reads your hereditary information and looks for variants that carry medical meaning. Four methods exist, with very different reach: a panel tests a fixed selection of genes, an array tests individual known positions in the genome, exome sequencing reads all protein-coding regions, and genome sequencing reads the entire genome. At YEARS the analysis runs as exome and genome sequencing with interpretation of more than 170 clinically curated risk genes. The distinction between data and findings matters: sequencing produces raw data, and it only becomes medically usable through physician interpretation in the context of your family history and your other values.

The German Genetic Diagnostics Act is unambiguous: a predictive genetic examination, meaning an examination for conditions you do not yet have, may only be ordered by a physician. Genetic counselling is mandatory before and after the examination, and for predictive testing it must be given by an appropriately qualified person. You must consent in writing, and you have the right not to be told a result. This chain is exactly what is missing from gene tests you buy online and post off yourself. There you receive a file, but no information duty, no counselling, and no medical assessment of what you are supposed to do with it.

That depends entirely on the type of finding, and this distinction is the most important one in the whole field. Monogenic findings with high penetrance, meaning ones that actually cause the condition in most carriers, such as BRCA1, BRCA2, Lynch syndrome or familial hypercholesterolaemia, are covered by guidelines and trigger defined consequences. Pharmacogenetic findings demonstrably change the dosing of certain drugs. Polygenic risk scores, by contrast, are research instruments: they shift a probability without establishing a diagnosis, and their predictive performance is far better documented in European cohorts than in others. Lifestyle genetics such as COMT or MTHFR we deliberately do not treat as actionable. The complete classification per procedure is on our evidence page.

Three groups benefit most clearly. First, people with a family history, meaning cancer, heart attack or dementia in parents or siblings, particularly at a young age of onset. Second, people with findings that lifestyle cannot explain, such as very high cholesterol despite a good diet. Third, people who regularly take several medications, for whom pharmacogenetics delivers concrete dosing guidance. An analysis is less useful if you treat it as a substitute for baseline diagnostics. Blood pressure, ApoB, Lp(a), HbA1c and imaging say more about your next ten years than your genome does. Genetics supplements these values, it does not replace them.

Your raw data and your findings belong to you. They are processed under the German Genetic Diagnostics Act and the GDPR, stored within the EU, and not passed to third parties: not to insurers, not to employers, and not for research purposes without your explicit and separate consent. In Germany employers and insurers may neither demand genetic examinations nor accept existing results, which is written into the Genetic Diagnostics Act. You can request deletion of your data. On request you receive your raw data in a common format so you can pass it to a physician continuing your care.

Genetics at YEARS is not a standalone product but part of the Ultimate programme at 16,900 euros. That includes exome and genome sequencing, interpretation of more than 170 risk genes, pharmacogenetics, epigenetics, microbiome, whole-body MRI, liquid biopsy and more than 230 biomarkers, plus medical counselling before and after the examination and three check-ins a year. The reason for the bundle is medical: a genetic finding without blood values, imaging and family history cannot be interpreted meaningfully. Statutory insurance does not reimburse. Privately insured patients and self-payers can claim parts of it, which is clarified in the intro call.
