Dry skin, eczema, blepharitis, photophobia and impaired sweating accompany the hair loss of Hypotrichosis 2, which is linked to a homozygous CST6 variant.
Decoding Iminoglycinuria: Understanding, Diagnosing, and Using Genetic Testing for Digenic Inheritance
Proline, hydroxyproline and glycine spill into the urine when both SLC36A2 and SLC6A20 carry mutations; the condition is usually benign but can lead to kidney stones.
Decoding the Genetic Mysteries of Intellectual Developmental Disorder, X-Linked, Syndromic 16
In MRXSA, a distinctive DNA methylation episignature has been reported alongside new CASK and ATRX variants that testing can detect to confirm a diagnosis.
Decoding the Mystery: Understanding and Diagnosing Profound Intellectual Disability
Limited communication and a need for constant support mark the most severe form of intellectual disability. A de novo SMARCB1 variant is among the causes cited.
