Summaries for Sotos Syndrome 2

UniProtKB/Swiss-Prot : 73 Sotos syndrome 2: A form of Sotos syndrome, a childhood overgrowth syndrome characterized by prenatal and postnatal overgrowth, developmental delay, mental retardation, advanced bone age, and abnormal craniofacial morphology. SOTOS2 patients have macrocephaly, long narrow face, high forehead, slender habitus, scoliosis, and unusual behavior characterized especially by anxiety.

MalaCards based summary : Sotos Syndrome 2, also known as malan syndrome, is related to marshall-smith syndrome and alacrima, achalasia, and mental retardation syndrome. An important gene associated with Sotos Syndrome 2 is NFIX (Nuclear Factor I X). Affiliated tissues include bone and eye, and related phenotypes are accelerated skeletal maturation and macrocephaly
