Summaries for Chromosome 17q11.2 Deletion Syndrome, 1.4-Mb

About this section
OMIM : 57 Approximately 5 to 20% of all patients with neurofibromatosis type I (162200) carry a heterozygous deletion of approximately 1.4 Mb involving the NF1 gene and contiguous genes lying in its flanking regions (Riva et al., 2000; Jenne et al., 2001), which is caused by nonallelic homologous recombination of NF1 repeats A and C (Dorschner et al., 2000). The 'NF1 microdeletion syndrome' is often characterized by a more severe phenotype than that observed in the majority of NF1 patients. In particular, patients with NF1 microdeletion often show variable facial dysmorphism, mental retardation, developmental delay, an excessive number of early-onset neurofibromas (Venturin et al., 2004), and an increased risk for malignant peripheral nerve sheath tumors (De Raedt et al., 2003). (613675)

MalaCards based summary : Chromosome 17q11.2 Deletion Syndrome, 1.4-Mb, also known as chromosome 17q11.2 deletion syndrome, 1.4mb, is related to chromosome 17q11.2 deletion syndrome and neurofibromatosis, type iv, of riccardi. An important gene associated with Chromosome 17q11.2 Deletion Syndrome, 1.4-Mb is DEL17Q11.2 (Chromosome 17q11.2 Deletion Syndrome). Affiliated tissues include bone, heart and brain, and related phenotypes are intellectual disability and global developmental delay
