Anemia, diabetes and sensorineural hearing loss together suggest TRMA, caused by SLC19A2 mutations that block thiamine transport; sequencing confirms the diagnosis.
A clot forming inside a brain blood vessel cuts off blood flow. Covers risk factors, Factor V Leiden and prothrombin G20210A findings, and family planning.
The gland looks normal yet cannot finish making hormone, causing congenital hypothyroidism. Targeted exome sequencing points to DUOX2, TSHR, TPO or SLC26A7.
Reduced TBG can still leave thyroid hormone levels normal, so SERPINA7 sequencing is what separates this partial deficiency from other thyroid conditions.
When toe walking persists past age 2, clinicians rule out cerebral palsy, muscular dystrophy and autism. NGS panels and exome sequencing may reveal inherited causes.
