The Detected MutationsTypes and Frequency in T-ALL Patients

Types of mutations	Mutation: nucleotide	Mutation: amino acid
No. of mutated samples (19/25)
Point mutation (19/25 )(1 active and 18 silent)
Exon 18: 1 Samples(active)	c.1866G>C	p.V596L
Exon 20: 18 Samples (silent)	c.2219C>T	p.A713A
Deletion mutation in Exon 18 ( 4 Samples)	c.1872delA	Frame shift mutation with unknown protein.

Among the detected mutations 2 novel ones were detected in exon 18, all of them were active, one was point mutation (c.1866G>C), and one was frame-shift mutation (c.1872delA) was detected in 4 samples.
