Genetics

Genetics on Zelomed

Human genetics ties together conditions (what can go wrong in the body), genes (units of instruction that are read to build and run cells), and chromosomes (packages of DNA—including the X and Y sex chromosomes and mitochondrial DNA). Our summaries condense reference material into plain language; they do not replace genetic counseling, testing decisions, or medical care.

What each area covers

• Genetic conditions — symptoms, frequency, causes, inheritance, and links to related genes when available.
• Genes — normal function, how changes may relate to disease, related conditions, and aliases.
• Chromosomes & mtDNA — chromosome-level context and related conditions where we have articles.

Using the genetics section

Choose the card that matches your starting point (a diagnosis name, a gene you heard about, or a chromosome from a lab report). Open articles in any order; cross-links help you move between a condition and the genes or regions discussed in genetics care. For treatment, screening, or family planning, bring what you read here to a qualified clinician or certified genetic counselor.
