Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM2 PM5 PP2 PP3_Strong PP5_Moderate

The NM_005859.5(PURA):c.692T>C(p.Phe231Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F231C) has been classified as Likely pathogenic.

Genes affected

PURA (HGNC:9701): (purine rich element binding protein A) This gene product is a sequence-specific, single-stranded DNA-binding protein. It binds preferentially to the single strand of the purine-rich element termed PUR, which is present at origins of replication and in gene flanking regions in a variety of eukaryotes from yeasts through humans. Thus, it is implicated in the control of both DNA replication and transcription. Deletion of this gene has been associated with myelodysplastic syndrome and acute myelogenous leukemia.

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr5-140114873-T-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 1335851.We mark this variant Likely_pathogenic, oryginal submissions are: {Likely_pathogenic=1, Uncertain_significance=1, Pathogenic=1}.
• PP2: Missense variant where missense usually causes diseases, PURA
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.983
• PP5: Variant 5-140114873-T-C is Pathogenic according to our data. Variant chr5-140114873-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 520768.Status of the report is criteria_provided_single_submitter, 1 stars.
