Description
This sequence change falls in intron 4 of the ELANE gene. It does not directly change the encoded amino acid sequence of the ELANE protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals with cyclic neutropenia (PMID: 23463630, 25912133). It has also been observed to segregate with disease in related individuals. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Experimental studies have shown that this variant disrupts mRNA splicing (PMID: 23463630, 25912133). This variant disrupts the c.597+5G nucleotide in the ELANE gene. Other variant(s) that disrupt this nucleotide have been determined to be pathogenic (PMID: 10581030, 23463630, 20049848, 30040071). This suggests that this nucleotide is clinically significant, and that variants that disrupt this position are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
