What is SETD5 syndrome?
Intellectual disability-facial dysmorphism syndrome due to SETD5 haploinsufficiency is a rare, syndromic intellectual disability characterized by intellectual disability of various severity, hypotonia, feeding difficulties, dysmorphic features, autism and behavioral issues.
What causes SETD5?
SETD5 Gene Haploinsufficiency in Three Patients With Suspected KBG Syndrome. Mendelian disorders of the epigenetic machinery (MDEMs), also named chromatin modifying disorders, are a broad group of neurodevelopmental disorders, caused by mutations in functionally related chromatin genes.
What does KBG syndrome mean?
KBG syndrome is a rare disorder that affects several body systems. “KBG” represents the surname initials of the first families diagnosed with the disorder. Common signs and symptoms in individuals with this condition include unusual facial features, skeletal abnormalities, and intellectual disability.
Is KBG syndrome life threatening?
Compared to conditions like spinal muscular atrophy, KBG syndrome is less common and less dangerous. There is no dramatic decrease in life expectancy due to KBG syndrome itself, but the side effects caused by the syndrome can be dangerous.
How is KBG diagnosed?
A diagnosis of KBG syndrome may be suspected after a thorough clinical evaluation, a detailed patient and family history, and the identification of characteristic physical findings.
Is KBG syndrome a disability?
KBG syndrome is characterized by intellectual disability associated with macrodontia of the upper central incisors as well as distinct craniofacial findings, short stature, and skeletal anomalies. Although believed to be genetic in origin, the specific underlying defect is unknown.
Is Noonan syndrome a disability?
The majority of children who are diagnosed with Noonan syndrome have average intelligence, although a small percentage have special educational needs, and some experience intellectual disability.
What is the SETD5 gene?
SETD5 (SET Domain Containing 5) is a Protein Coding gene. Diseases associated with SETD5 include Mental Retardation, Autosomal Dominant 23 and Cornelia De Lange Syndrome. Among its related pathways are PKMTs methylate histone lysines.
How does SETD5 regulate brain development and function?
SETD5 Regulates Chromatin Methylation State and Preserves Global Transcriptional Fidelity during Brain Development and Neuronal Wiring Mutations in one SETD5 allele are genetic causes of intellectual disability and autistic spectrum disorders. However, the mechanisms by which SETD5 regulates brain development and function remain largely elusive.
What diseases are associated with SETD5?
Diseases associated with SETD5 include Intellectual Developmental Disorder, Autosomal Dominant 23 and Cleft Lip . Among its related pathways are Malignant pleural mesothelioma and PKMTs methylate histone lysines . An important paralog of this gene is KMT2E.
Is SETD5 an epigenetic driver of PDAC resistance to Meki?
Oncogenic KRAS signaling is a hallmark of PDAC, a lethal malignancy with few treatment options. A major roadblock in deploying therapies targeting the KRAS-MAPK pathway is the rapid emergence of resistant cancer cells. Here, we show that SETD5 is a clinically actionable epigenetic driver of PDAC resistance to MEKi.
