Prognosis
Prognosis The prognosis is variable and depends on the severity and extent of congenital malformations. The documents contained in this web site are presented for information purposes only. [orpha.net]
Etiology
Etiology The syndrome is caused by a microdeletion of 1.7 to 6.1 Mb in size in chromosome 15q24 which usually results from nonallelic homologous recombination (NAHR). [orpha.net]
Epidemiology
Summary Epidemiology The prevalence of 15q24 deletion syndrome is unknown. To date, 19 cases with clinical data and detailed mapping of genomic breakpoints have been reported. [orpha.net]
