Shashi-Pena syndrome is a rare neurologic disease characterized by delayed psychologic and motor development, variable intellectual disability, and poor muscle tone (hypotonia). Described features include tall stature, a large head (macrocephaly), deep palmar creases, and distinct facial features. These features include a port-wine birthmark on the forehead (glabellar nevus flammeus), widely spaced eyes (hypertelorism), arched eyebrows, prominent eyes, a broad nasal tip and minor ear abnormalities. Some patients may also have heart abnormalities (such as atrial septal defect), feeding difficulties, changes in bone mineral density, advanced bone age, aggressive and/or autistic behavior and/or seizures. MRI of the brain may show a loss of neuronal cells (cerebral atrophy). Blood exams may show episodes of low sugar (hypoglycemia), and in some cases, elevated liver enzymes (transaminases), high levels of insulin (hyperinsulinemia), and high fat levels (hyperlipidemia). Shashi-Pena syndrome is caused by variations (mutations) in the ASXL2 gene, which is important for neurologic and bone development, heart function, and glucose and lipid metabolism. Treatment depends on the symptoms and may include medication and behavioral therapy, as well as surgical procedures if needed.
MalaCards based summary : Shashi-Pena Syndrome, is also known as shapns. An important gene associated with Shashi-Pena Syndrome is ASXL2 (ASXL Transcriptional Regulator 2). Affiliated tissues include bone, eye and brain, and related phenotypes are macrocephaly and hypertelorism OMIM : 57 Shashi-Pena syndrome is a neurodevelopmental syndrome characterized by delayed psychomotor development, variable intellectual disability, hypotonia, facial dysmorphism, and some unusual features, including enlarged head circumference, glabellar nevus flammeus, and deep palmar creases. Some patients may also have atrial septal defect, episodic hypoglycemia, changes in bone mineral density, and/or seizures (summary by Shashi et al., 2016).
