Chromosome 15q14 deletions and loss of the MEIS2 gene
0 Comment
This summary discusses chromosome 15q14 deletions and the loss of the MEIS2 gene. 15q14 deletions (deletions occurring within this region of the long arm of chromosome 15) are known to cause cleft palate, intellectual disability, congenital heart defects, and facial dysmorphism. Loss of the MEIS2 gene located within 15q14 has... Read More

Prenatal profile of Pallister-Killian Syndrome
Determining a prenatal profile for Pallister-Killian Syndrome leads to earlier genetic counseling and symptom management. Pallister-Killian syndrome (PKS) is a genetic condition which results in a variety of symptoms, including facial dysmorphisms, skin discolorations, intellectual disability, developmental delay, congenital heart defects, congenital diaphragmatic hernia (abdominal hernias that occur in fetuses),...

De Novo Mutations of the CCNK gene cause a Neurodevelopmental Disorder
De Novo Mutations of CCNK Cause a Syndromic Neurodevelopmental Disorder with Distinctive Facial Dysmorphism Cytogenetic location 14q32.2 Neurodevelopment is a complex process that requires the coordination and regulation of several cellular activities. This regulation is maintained through precise control of when genes are transcribed. Gene transcription is the process of... Read More

Duplication 14q32, leukemia and myelodysplastic syndrome
Familial myeloid malignancy syndrome associated with the duplication of chromosome 14q32. Myeloid neoplasms refer to conditions involving abnormal growth and function of white blood cells. About 10% of patients with myeloid neoplasms are thought to have a genetic predisposition to myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). A recent... Read More

Syndromes hidden within the 16p11.2 deletion region
16p11.2 is a region of chromosome 16 particularly prone to deletions and duplications. Copy number variations (CNVs) are defined as specific regions within a chromosome that are either deleted or duplicated. CNVs can either be inherited or can occur spontaneously in patients during development. The effects of CNVs are difficult... Read More
