Description

The p.N898S variant (also known as c.2693A>G), located in coding exon 17 of the ABCA3 gene, results from an A to G substitution at nucleotide position 2693. The asparagine at codon 898 is replaced by serine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear.
