Genes affected
HNRNPU (HGNC:5048): (heterogeneous nuclear ribonucleoprotein U) This gene encodes a member of a family of proteins that bind nucleic acids and function in the formation of ribonucleoprotein complexes in the nucleus with heterogeneous nuclear RNA (hnRNA). The encoded protein has affinity for both RNA and DNA, and binds scaffold-attached region (SAR) DNA. Mutations in this gene have been associated with epileptic encephalopathy, early infantile, 54. A pseudogene of this gene has been identified on chromosome 14. [provided by RefSeq, Jun 2017]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -15 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.74).
BP6
Variant 1-244864020-G-A is Benign according to our data. Variant chr1-244864020-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 414096.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=2.08 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000116 (17/1460686) while in subpopulation AMR AF = 0.000314 (14/44612). AF 95% confidence interval is 0.000189. There are 0 homozygotes in GnomAdExome4. There are 8 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check.
BS2
High AC in GnomAdExome4 at 17 AD gene.
