Genes affected

HNRNPR (HGNC:5047): (heterogeneous nuclear ribonucleoprotein R) This gene encodes an RNA-binding protein that is a member of the spliceosome C complex, which functions in pre-mRNA processing and transport. The encoded protein also promotes transcription at the c-fos gene. Alternative splicing results in multiple transcript variants. There are pseudogenes for this gene on chromosomes 4, 11, and 10.

HNRNPR Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with dysmorphic facies and skeletal and brain abnormalities

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), G2P
• syndromic intellectual disability

ACMG classification

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.13 CDS is truncated, and there are 2 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-23310702-G-A is Pathogenic according to our data. Variant chr1-23310702-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 520674.Status of the report is criteria_provided_single_submitter, 1 stars.
