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 made for transcript

Verdict is Benign. Variant got -15 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.49).
BP6
Variant 1-244858071-G-A is Benign according to our data. Variant chr1-244858071-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 446404.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=1.16 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.000146 (214/1461730) while in subpopulation NFE AF= 0.000184 (205/1111870). AF 95% confidence interval is 0.000163. There are 0 homozygotes in gnomad4_exome. There are 93 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
