Underdeveloped lungs leave a newborn struggling to breathe. Chest X-rays and pulse oximetry confirm it, while genetic testing can point to an inherited cause.

Movement problems, psychiatric changes and speech or gait difficulty vary case by case in ANBIA1; COASY mutations and MRI findings anchor the diagnosis.

Hypotonia, weakness and delayed motor milestones define CNMDU1; muscle biopsy studies of core formation and RYR1 research explain what genetic testing adds.

Case reports on Fahr's disease, fragile X premutation and a PSEN1 mutation show how testing can connect psychiatric symptoms with cataracts appearing early.

Lipids collect in the liver, spleen and brain in this intermediate form of Niemann-Pick type C, and NPC1 or NPC2 testing confirms it and identifies carriers.

Enlarged liver and spleen, swallowing difficulty and poor muscle coordination appear in NPD-D, which is traced to NPC1 or NPC2 mutations through DNA sequencing.

Encephalopathy, Hermansky-Pudlak syndrome, prenatal cardiomyopathy and persistent EV-HPV infections are presented here as features of this rare disorder.

Monogenic causes such as MC4R, LEP and POMC, obesity-related syndromes, and gene-environment interactions each shape risk. Appetite-related variants are also covered.
