Chromosome 10p15.3 deletion and neurological symptoms
0 Comment
Chromosome 10p15.3 is the most distal segment of 10p. The deletions within this area are characterized by developmental delay, motor skill delay, speech disorders, brain abnormalities, and seizures. Two genes within this region – ZMYND11 and DIP2C – are commonly deleted due to this condition, and loss of these is... Read More
