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 Likely_benign. Variant got -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), HNRNPU. . Gene score misZ 3.3718 (greater than the threshold 3.09). Trascript score misZ 3.5021 (greater than threshold 3.09). GenCC has associacion of gene with developmental and epileptic encephalopathy, 54, complex neurodevelopmental disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.20465809).
BP6
Variant 1-244863869-C-T is Benign according to our data. Variant chr1-244863869-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 574129.Status of the report is criteria_provided_single_submitter, 1 stars.
