Mutations in the NOP10 gene disrupt telomere maintenance, producing the abnormal skin pigmentation, nail dystrophy and leukoplakia seen in this rare subtype.

A homozygous missense mutation in OFD1 has been tied to this subtype, whose triad of skin pigmentation, nail dystrophy and oral leukoplakia varies between patients.

Endothelial dystrophy, iris hypoplasia, congenital cataract and stromal thinning form the acronym, and a single-base change in the miR-184 seed region causes them.

Because this dominant form carries a risk of cardiac complications, LMNA analysis can identify affected people before weakness and contractures show up.

Differences in immune response and inflammation can raise the chance that an infection leads to acute brain dysfunction, the susceptibility described as EAIS4.

Compound heterozygous SLC26A2 variants disturb chondrocyte proliferation in this autosomal recessive skeletal dysplasia, bringing joint pain and stiffness.

Dilations in the retinal arteries, sometimes with supravalvular pulmonic stenosis, define FRAM and can lead to retinal hemorrhage or vision loss.

Sitting on chromosome 9, FANCG encodes a protein that repairs DNA interstrand crosslinks; sequencing it confirms the subtype and informs transplant planning.
