Genes affected

ASZ1 (HGNC:1350): (ankyrin repeat, SAM and basic leucine zipper domain containing 1) Predicted to be involved in gamete generation and piRNA metabolic process. Predicted to be located in cytoplasm. Predicted to be active in pi-body. [provided by Alliance of Genome Resources, Apr 2022]

ASZ1 links:

CFTR (HGNC:1884): (CF transmembrane conductance regulator) This gene encodes a member of the ATP-binding cassette (ABC) transporter superfamily. The encoded protein functions as a chloride channel, making it unique among members of this protein family, and controls ion and water secretion and absorption in epithelial tissues. Channel activation is mediated by cycles of regulatory domain phosphorylation, ATP-binding by the nucleotide-binding domains, and ATP hydrolysis. Mutations in this gene cause cystic fibrosis, the most common lethal genetic disorder in populations of Northern European descent. The most frequently occurring mutation in cystic fibrosis, DeltaF508, results in impaired folding and trafficking of the encoded protein. Multiple pseudogenes have been identified in the human genome. [provided by RefSeq, Aug 2017]

The c.1091A>G (p.N364S) alteration is located in exon 11 (coding exon 11) of the ASZ1 gene. This alteration results from a A to G substitution at nucleotide position 1091, causing the asparagine (N) at amino acid position 364 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
