Poor weight gain, breathlessness and repeated chest infections point to atrioventricular septal defect; gene testing separates it from ASD and VSD in unclear cases.

Loss-of-function CLCNKB variants track with earlier diagnosis and higher chronic kidney disease risk, alongside lab findings and cases recognised in elderly patients.

Eyes that are much smaller than usual at birth can mean vision loss or blindness. Next-generation sequencing is described as a way to find the variants involved.

A 24-base pair deletion in the ABO gene causes a hereditary splice site defect tied to this rare group. DNA testing from blood or saliva can detect it.

Linkage analysis across 1,812 families found genetic heterogeneity behind BMI, and the page sets BMIQTL4 beside BDNF rs6265 findings and AutoQTL methods.

Discover the role of genetic testing in diagnosing Campomelic Dysplasia with Autosomal Sex Reversal, guiding treatment, and supporting research for this rare genetic disorder.
