Repeated bacterial infections in infancy point to a severe neutrophil shortage. ELANE is the usual cause, and wider gene panels are used when no ELANE change is found.

Porphyrins build up when coproporphyrinogen oxidase is deficient, bringing abdominal pain, vomiting and muscle weakness; hereditary coproporphyria is autosomal dominant.

Male fertility can be affected by smaller testes; research cited links an X-linked RBBP7 variant, skin inflammation and obesity to impaired testicular function.

PMP22, MPZ, PRX and EGR2 are genes analyzed when demyelinating motor and sensory neuropathy is suspected, and next-generation sequencing reads them together.

Children who are not walking independently by 18 months may have an underlying cause; medical history, physical examination, imaging and blood tests come first.

Discover the role of genetic testing in diagnosing delayed speech and language development, and learn how it guides personalized intervention strategies for improved communication.

Missing delta-globin chains define this rare autosomal recessive blood disorder; blood tests suggest it, but DNA analysis separates it from other thalassemias.
