17q11.2 microdeletions, which include the neurofibromatosis type 1 (NF1) gene region, are responsible for the NF1 microdeletion syndrome, observed in 4.2% of all NF1 patients.
NF1 microdeletion syndrome is more severe than NF1 caused by gene mutations, with individuals exhibiting facial dysmorphisms, developmental delay (DD), intellectual disability (ID), and excessive neurofibromas.
NF1 microdeletion syndrome is more severe than NF1 caused by gene mutations, with individuals exhibiting facial dysmorphisms, developmental delay (DD), intellectual disability (ID), and excessive neurofibromas.
Neurofibromatosis type 1 (NF1) microdeletion syndrome is caused by haploinsufficiency of the NF1 gene and of gene(s) located in adjacent flanking regions.
