Genes affected

HNRNPA1 (HGNC:5031): (heterogeneous nuclear ribonucleoprotein A1) This gene encodes a member of a family of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs), which are RNA-binding proteins that associate with pre-mRNAs in the nucleus and influence pre-mRNA processing, as well as other aspects of mRNA metabolism and transport. The protein encoded by this gene is one of the most abundant core proteins of hnRNP complexes and plays a key role in the regulation of alternative splicing. Mutations in this gene have been observed in individuals with amyotrophic lateral sclerosis 20. Multiple alternatively spliced transcript variants have been found. There are numerous pseudogenes of this gene distributed throughout the genome. [provided by RefSeq, Feb 2016]

HNRNPA1 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 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), HNRNPA1. . Gene score misZ 2.8218 (greater than the threshold 3.09). Trascript score misZ 4.1111 (greater than threshold 3.09). GenCC has associacion of gene with amyotrophic lateral sclerosis, inclusion body myopathy with Paget disease of bone and frontotemporal dementia, inclusion body myopathy with early-onset Paget disease with or without frontotemporal dementia 3, amyotrophic lateral sclerosis type 20.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.843
• PP5: Variant 12-54283845-A-T is Pathogenic according to our data. Variant chr12-54283845-A-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 65451.Status of the report is criteria_provided_single_submitter, 1 stars.
