Introduction: Digital polymerase chain reaction (PCR) studies for clonal disease monitoring in B-acute lymphoblastic leukemia patients are currently limited due to the heterogeneous nature of mutations, which limit cost-effective assay designs.
Materials And Methods: In this study, 70 samples (14 relapse and 56 sequential therapy samples) were tested for 13 recurrent mutations identified on deep sequencing in our published cohort (KRAS, NRAS, NT5C2, PMS2, UHRF1, KMT2D, and TP53 genes) via a novel triplex digital PCR assay.
Results And Discussion: A total of seven major clones of NRAS [five] and NT5C2 [two] were noted in six out of 14 (43%) relapse patients, accounting for 44% of early relapses.
Introduction: Telomere length related studies are limited in pediatric marrow failure cases due to difficulty in establishing population specific age related normograms. Moreover, there is paucity of data related to clinical relevance of telomere length in idiopathic aplastic anemia (IAA) and non telomere biology inherited bone marrow failure syndrome (IBMFS) cases.
Methodology: Hence, in current study we investigated Relative telomere length (RTL) by RQ-PCR in 83 samples as: healthy controls (n = 44), IAA (n = 15) and IBMFS (n = 24).
