Genes affected
CEBPA (HGNC:1833): (CCAAT enhancer binding protein alpha) This intronless gene encodes a transcription factor that contains a basic leucine zipper (bZIP) domain and recognizes the CCAAT motif in the promoters of target genes. The encoded protein functions in homodimers and also heterodimers with CCAAT/enhancer-binding proteins beta and gamma. Activity of this protein can modulate the expression of genes involved in cell cycle regulation as well as in body weight homeostasis. Mutation of this gene is associated with acute myeloid leukemia. The use of alternative in-frame non-AUG (GUG) and AUG start codons results in protein isoforms with different lengths. Differential translation initiation is mediated by an out-of-frame, upstream open reading frame which is located between the GUG and the first AUG start codons. [provided by RefSeq, Dec 2013]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.39).
BP6
Variant 19-33302013-C-T is Benign according to our data. Variant chr19-33302013-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 239923.We mark this variant Likely_benign, oryginal submissions are: {Benign=3, Likely_benign=1, Uncertain_significance=1}. Variant chr19-33302013-C-T is described in Lovd as [Likely_benign].
BP7
Synonymous conserved (PhyloP=0.035 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00283 (420/148578) while in subpopulation NFE AF= 0.00429 (286/66658). AF 95% confidence interval is 0.00388. There are 1 homozygotes in gnomad4. There are 220 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 420 AD gene.
