Development of simple and effective PCR based assay to detect PCCA mutation (c.425G > A) among Saudi carriers and functional study of the homozygous PCCA mutations.

ABSTRACT: The aim of this study is to develop a rapid and effective method to screen for Saudi carriers of one of the most common propionic acidemia mutations (c.425G > A) and to study the functional impact of this mutation. Using allele-specific primers, we have developed a qPCR assay that clearly distinguishes heterozygotes from mutated and wild type homozygotes that overcome the dependence on labor-intensive gene sequencing. We show here that (i) qPCR rapid test has strong accuracy in detecting (c.425G > A) mutation in heterozygotes and homozygotes individuals and that the Ct-value cut-offs were estimated to be and 23.37 ± 0.04 (CV-6 %, 95 %CI-7.25) for homozygote, 25.06 ± 0.02 (CV-3.5 %, 95 %CI-7.85) for heterozygote PCCA c.425G > A mutation and 29.55 ± 0.002 (CV-11 %, 95 %CI-1.41)
