Variant summary
Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PM2PP3_StrongPP5_Moderate
The NM_000101.4(CYBA):c.155T>C(p.Leu52Pro) variant causes a missense change. The variant allele was found at a frequency of 0.00000248 in 1,610,800 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. L52L) has been classified as Likely benign.

The L52P variant in the CYBA gene has been reported previously in the apparently homozygous state inan individual with chronic granulomatous disease (Rae et al., 2000). The L52P substitution was not observedin approximately 6,500 individuals of European and African American ancestry in the NHLBI ExomeSequencing Project, indicating it is not a common benign variant in these populations. The L52P variant isa semi-conservative amino acid substitution, which may impact secondary protein structure as theseresidues differ in some properties. This substitution occurs at a position that is conserved across species. Insilico analysis predicts this variant is probably damaging to the protein structure/function. Missensevariants in nearby residues (L51Q, E53V, P55R) have been reported in the Human Gene MutationDatabase in association with chronic granulomatous disease (Stenson et al., 2014), supporting thefunctional importance of this region of the protein. We interpret L52P as a pathogenic variant.
