Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 1P and 6B. PP3BP4_ModerateBS2

The NM_001077350.3(NPRL3):c.1567C>T(p.Arg523Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00011 in 1,613,232 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R523L) has been classified as Uncertain significance.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 7: BayesDel_addAF, BayesDel_noAF, Cadd, Dann, phyloP100way_vertebrate, REVEL, REVEL [when AlphaMissense, max_spliceai, M_CAP, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.19069755).

BS2

High AC in GnomAd4 at 9 AD gene.
