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]

ACMG classification

Verdict is Benign. Variant got -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.68).
• BP6: Variant 9-83970263-C-T is Benign according to our data. Variant chr9-83970263-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 755886.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-2.49 with no splicing effect.
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000246 (36/1461518) while in subpopulation MID AF= 0.00347 (20/5768). AF 95% confidence interval is 0.0023. There are 0 homozygotes in gnomad4_exome. There are 21 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High AC in GnomAdExome at 6 AD gene.
