Objectives.: To determine the frequency of the ten most common mutations of the CFTR gene reported in Latin Americausing amplification-refractory mutation system-polymerase chain reaction (ARMS-PCR) in patients with cystic fibrosis (CF) in two referral hospitals in Peru during the year 2014.
Materials And Methods.: The frequency of the ten most common mutations of the CFTR gene was assessed in patients of the Hospital Nacional Edgardo Rebagliati Martins and the Instituto Nacional de Salud del Niño, both located in Lima, Peru. Blood samples were collected from 36 patients with CF, and the ARMS-PCR technique was used to determine the presence of these mutations.
Results.: The study group included 73.5% of patients with a known diagnosis of CF in the country when the study was carried out. ARMS-PCR allowed three of the mutations to be identified in a combined 30.6% of the alleles from patients with CF, and 64.9% of the mutated alleles were not identified. The mutations found were p.Phe508del (22,2%), p.Gly542* (6,9%), and p.Arg1162* (1,4%).
Conclusions.: There is significant variability in both the frequency and type of mutations present in our study population and in what has been reported in other Latin American countries. It is necessary to perform studies that use complete sequencing technology for the CFTR gene to identify other mutations present in our population.

Autosomal recessive proximal renal tubular acidosis (AR-pRTA) with ocular abnormalities is a rare syndrome caused by variants in the SLC4A4 gene, which encodes Na/HCO3 cotransporter (NBCe1). The syndrome primarily affects the kidneys, but also causes extra-renal manifestations. Pancreatic type NBCe1 is located at the basolateral membrane of the pancreatic ductal cells and together with CFTR chloride channel, it is involved in bicarbonate secretion.

Sarcoglycanopathies are rare forms of severe muscular dystrophies currently without a therapy. Mutations in sarcoglycan (SG) genes cause the reduction or absence of the SG-complex, a tetramer located in the sarcolemma that plays a protective role during muscle contraction. Missense mutations in SGCA, which cause α-sarcoglycanopathy, otherwise known as LGMD2D/R3, lead to folding defective forms of α-SG that are discarded by the cell quality control.

Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in the gene. Currently, CFTR modulators are the most effective treatment for CF; however, they may not be suitable for all patients. A representative and convenient model is needed to screen therapeutic agents under development.

Objectives: To determine the diagnostic yield of cystic fibrosis (CF) using a two-tiered genetic testing approach. Although newborn screening includes CF, this typically only covers a selection of common genetic variants, and with over 2000 reported in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, we hypothesised that patients will be missed and present clinically later in life.
Design: A retrospective study over a 5-year period (January 2018-December 2022).

Background: Pathogenic mutations in the CFTR gene disrupt the normal function of the chloride ion channel CFTR protein, resulting in Cystic Fibrosis (C.F.).
