Whole exome sequencing (WES)    is   a    technique used to analyze all the protein-coding  regions  of  a person’s genome,  nown    as   the   exome.   These exonic regions make up about 1-2%   of   the   entire genome but contain the    majority        of      known  disease-causing   mutations.    WES   helps  identify genetic mutations that may lead to various inherited disorders or conditions. It involves  sequencing   the exons, followed by  the   identification    of    genetic variants and comparison with reference  databases. WES is often used when other genetic tests   fail   to provide a diagnosis for   unexplained   symptoms.  It provides a more comprehensive   understanding   of genetic    contributions   to  disease   than   targeted sequencing. This test is valuable  for   rare    genetic disorders, offering insights for diagnosis, treatment, and genetic counseling.
