Furthermore, we suggest that FISH analysis with a probe for the PML gene be performed in patients with these physical findings. [experts.nebraska.edu]
Conclusion: The molecular characterisation of these patients suggests that the core cognitive features of the 15q24 microdeletion syndrome, including developmental delays and severe speech problems, are largely due to deletion of genes in a 1.1-Mb critical [ohsu.pure.elsevier.com]
Despite the differing extent of the deletions in our patients, the phenotypic similarities observed between all four cases suggest that the deletion of 15q24 may represent a clinically distinct entity and suggest that a haploinsufficient gene or genes [academic.oup.com]

Prognosis
Prognosis The prognosis is variable and depends on the severity and extent of congenital malformations. Visit the Orphanet disease page for more resources. [rareguru.com]
Prognosis The prognosis for individuals with 15q24 deletion syndrome depends on the severity and extent of congenital malformations. [ojrd.biomedcentral.com]
Parental aCGH and/or FISH studies are recommended to provide accurate genetic counseling and guidance regarding prognosis, recurrence risk, and reproductive options. [springermedizin.de]
Conclusions: The obtained data argue that detection of such a deletion in the region 15q24-ter associated with CDH likely predicts a poor prognosis. [karger.com]
Etiology
Sequencing of genes in the 15q24 interval in large ASD and intellectual disability samples may identify mutations of etiologic importance in the development of these disorders. https://www.hal.inserm.fr/inserm-00622567 Contributeur : Ed. [hal.inserm.fr]
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). [rareguru.com]
Nevertheless, one apparent mutation in the FOG2 gene has been described in an isolated patient with diaphragmatic eventration (thinning of the diaphragm),4 supporting the expected genetic etiology of a proportion of CDH patients. [nature.com]
The etiology of the recurrent infections is currently unknown. Immunodeficiency could be the underlying cause; however, immunologic work up has not been reported in any of those individuals. [ojrd.biomedcentral.com]

Pathophysiology
This deletion includes the MBD5 gene, which is implicated in the pathophysiology of seizures. Stereotyped behaviors are also present and these are similar to Rett syndrome or Angelman syndrome. [scielo.br]
Prevention
The PML gene on chromosome 15 provides instructions for a protein that acts as a tumor suppressor, which means it prevents cells from growing and dividing too rapidly or in an uncontrolled way. [medlineplus.gov]
