Summary Introduction

Case summary:

Jesse is 2 years old, presented with difficulty in walking and poor control of movements. His muscles are slow to relax and remain in the state of contraction even after movement is performed. Genetic analysis showed he is suffering from a genetic disorder that causes the pumps in the sarcoplasmic reticulum to work slower than normal speed.

Characters in the case:

Jesse has a genetic defect that makes sarcoplasmic reticulum slower.

Adequate information:

Jesse has difficulty in walking and poor control of movements.

His muscles are slow to relax after movement is finished.

He has a genetic defect that makes his sarcoplasmic reticulum slower.

To determine:
