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 -20 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.76).
BP6
Variant 1-244856720-C-A is Benign according to our data. Variant chr1-244856720-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 414106.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00282 (429/152326) while in subpopulation AFR AF = 0.00994 (413/41560). AF 95% confidence interval is 0.00915. There are 2 homozygotes in GnomAd4. There are 210 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 429 AD gene.
