CN comparison of EGFR by array and FISH

Sample	MIP array		FISH
	EGFR CN	Repeat	EGFR CN
EGFR-01	37		>20
EGFR-02	51	37	>10
EGFR-03	8		>13.20
EGFR-04	61		>20
EGFR-06	47		>15.98
EGFR-07	13.33a		6.00
EGFR-09	34	27	>16.0
EGFR-10	22	18	16.95

^aThe tumor content could not be determined, likely due to the presence of more than 2 cell populations with differing degrees of CNCs. The CN reported here is therefore an average of the EGFR CN across the entire tissue biopsy
