Real questions from health communities, answered with cited research from PubMed and Vellito's article corpus. Plain language, no medical advice. How this works.
Exome sequencing finds a genetic cause in about 19% of prenatal cases, with higher rates for specific conditions like nonimmune hydrops fetalis.
Genome sequencing can find diagnoses for many undiagnosed genetic disorders in newborns, with overall success rates around 19% to 26% depending on the study and test type.
Families with suspected Lynch Syndrome typically carry germline mutations in four specific DNA mismatch repair genes: MLH1, MSH2, MSH6, and PMS2.
Current research finds no overall genetic link between kidney function and Alzheimer disease, though some shared biological pathways may exist.
Specific genetic variants in the PON1 gene can change how well the enzyme works, which directly influences a person's risk for developing liver fibrosis and related metabolic…
Research shows that restless legs syndrome (RLS) has both shared genetic factors across different populations and unique genetic markers specific to certain ancestries.
Genetic ancestry does affect risk for restless legs syndrome, with specific risk genes found in African and Latin American populations that differ from those in European groups.
Genetic studies show that cannabis use and sleep disorders share specific genetic risks, particularly for insomnia and nighttime activity levels.
Yes, trauma exposure can cause epigenetic changes in stress and immune pathways, as shown by multiple studies.
Yes, polygenic risk scores (PRS) for anxiety and depression show stronger associations with comorbid anxiety-depression cases than with either disorder alone, suggesting shared…
Yes, a specific saliva test measuring IgA antibodies to EBNA1 protein can accurately predict NPC risk, with sensitivity up to 90% and specificity over 91%.
Yes, a large genetic study found that PTSD shares many genetic risk factors with other internalizing disorders like anxiety and depression, but also has unique genetic influences.
Yes, a meta-analysis of the VA Million Veterans Program identified 17 new genetic loci in European, 4 in African, and 3 in Hispanic veteran populations for Alzheimer's disease.
We pull real patient questions from public Reddit health communities (r/AskDocs, r/diabetes, r/menopause, etc.). Each question is rewritten into a generic medical question (no personal details), then answered by an AI using only cited sources from Vellito's article database and PubMed. A second AI independently scores each answer for accuracy and citation fidelity before publication. Answers below the safety threshold or touching emergency, dosing, or pediatric topics are queued for human review and never auto-published.
