X-Linked Syndromic Mental Retardation Type Raymond

Lujan-Fryns Syndrome

In conclusion, we present here a de novo 500 kb triplication at Xq25 that overlaps almost perfectly with several previously reported microduplications in this region and presenting with a similar phenotype. [alabmed.com]

Signs and symptoms ALD can present in different ways. The different presentations are complicated by the pattern of X-linked recessive inheritance. [checkrare.com]

Peripheral neuropathy may be present and contribute to motor disability. MRI findings are consistent with hypomyelination with minimal or extremely slow myelination. Myelin is present in the internal capsule and is usually normal in the cerebellum. [rarediseases.org]
