Presentation
Individuals with this syndrome may also present with seizures. Since the patient’s mother is mosaic for this variant, this may explain her history of epilepsy. [mnglabs.com]

Luscan-Lumish syndrome (LLS) is characterized by macrocephaly, intellectual disability, speech delay, low sociability, and behavioral problems. [ncbi.nlm.nih.gov]
These individuals typically have some degree of developmental delays/intellectual disability and/or behavioral issues and autistic features. These features are variable and range from mild behavioral problems to severe intellectual disability. [luscan-lumish.org]

Workup
• Based on expert opinion, workup for tall stature that exceeds the individual's mid-parental height should include assessment of growth velocity and should consider full blood counts, complete biochemical analysis, IGF-I, IGFBP-3, free T4, and TSH, [frontiersin.org]

Prognosis
The overgrowth syndromes are important to diagnose, not just for accurate genetic counseling, but also for knowledge surrounding cancer surveillance and prognosis. [karger.com]
Due to the AV fistula, high-output heart failure can develop in about 31% of cases and almost 10% manifest distal arterial ischemia, making the overall prognosis of this syndrome worse than KTS (103). [frontiersin.org]

Other etiologies include familial tall stature (constitutional tall stature), precocious puberty, obesity, Marfan syndrome, homocystinuria, Klinefelter syndrome, and 47,XYY syndrome (4). • Segmental overgrowth—A phenotype of excessive growth that is confined [frontiersin.org]
Prevention
Additionally, prevention of obesity should be an important point of attention for patients diagnosed with a SETD2-related overgrowth syndrome. [onlinelibrary.wiley.com]
In polycystic ovary syndrome, abnormal hormone levels prevent follicles from growing and maturing to release egg cells. Instead, these immature follicles accumulate in the ovaries. Affected women can have 12 or more of these follicles. [ncbi.nlm.nih.gov]
