Clinical and genetic characteristics of young-onset diabetes with concurrent mitochondrial m.3243A>G and CEL gene mutations: A case report

Table 1 Pancreatic islet function test

Time (minute)	0	60	120	180	Reference range
Blood glucose (mmol/L)	4.45	10.97	19.06	20.57	3.9-6.1
C-peptide (ng/mL)	0.16	0.47	1.28	1.81	1.1-4.4

The pancreatic function assessment was performed using an oral glucose tolerance test.

Nerve	CV		Findings
SNC testing
Right median nerve	Middle finger-wrist	41 m/s	Slowed
Right ulnar nerve	Little finger-wrist	41 m/s	Slowed
Left median nerve	Middle finger-wrist	44 m/s	Slowed
Left superficial	Calf-medial malleolus	38 m/s	Slowed
Right superficial	Calf-medial malleolus	39 m/s	Slowed
Right sural nerve	Lateral malleolus-sura	43 m/s	Slowed
MNC testing
Right median nerve	Distal latency	4.1 ms	Prolonged
	Elbow-wrist CV	46 m/s	Slowed
