Genes affected
KLF1 (HGNC:6345): (KLF transcription factor 1) This gene encodes a hematopoietic-specific transcription factor that induces high-level expression of adult beta-globin and other erythroid genes. The zinc-finger protein binds to the DNA sequence CCACACCCT found in the beta hemoglobin promoter. Heterozygous loss-of-function mutations in this gene result in the dominant In(Lu) blood phenotype.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.34).
BP6
Variant 19-12884897-C-T is Benign according to our data. Variant chr19-12884897-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 2129029.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=2.7 with no splicing effect.
BS2
High AC in GnomAdExome4 at 5 AD,BG gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
