Genes affected

HNRNPK (HGNC:5044): (heterogeneous nuclear ribonucleoprotein K) This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene is located in the nucleoplasm and has three repeats of KH domains that binds to RNAs. It is distinct among other hnRNP proteins in its binding preference; it binds tenaciously to poly(C). This protein is also thought to have a role during cell cycle progession. Several alternatively spliced transcript variants have been described for this gene, however, not all of them are fully characterized. [provided by RefSeq, Jul 2008]

HNRNPK-AS1 (HGNC:56061): (HNRNPK antisense RNA 1)

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the HNRNPK gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 15 curated pathogenic missense variants (we use a threshold of 10). The gene has 4 curated benign missense variants. Gene score misZ: 3.9922 (above the threshold of 3.09). Trascript score misZ: 3.2967 (above the threshold of 3.09). GenCC associations: The gene is linked to Au-Kline syndrome, neurodevelopmental disorder-craniofacial dysmorphism-cardiac defect-hip dysplasia syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.39055377).
