The Girl Who Never Grew Up

The video discusses the predictable pattern of human growth and introduces a rare condition called neotenic complex syndrome (NCS), where individuals remain in a toddler-like state throughout their lives. The first documented case involved a girl who did not develop past toddlerhood, despite having typical chromosomes. Research into NCS has revealed unique genetic mutations affecting gene expression, particularly in transcription regulation. Although these findings provide clues, the exact cause of NCS remains unknown. Further research is needed to understand the role of epigenetics and gene expression in this condition, which could lead to treatments for NCS and other developmental disorders.

What role do mutations in genes play in the context of NCS according to the studies conducted?
