Genes affected
HNRNPA3 (HGNC:24941): (heterogeneous nuclear ribonucleoprotein A3) Enables RNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Located in nucleoplasm. Part of catalytic step 2 spliceosome. [provided by Alliance of Genome Resources, Apr 2022]
NFE2L2 (HGNC:7782): (NFE2 like bZIP transcription factor 2) This gene encodes a transcription factor which is a member of a small family of basic leucine zipper (bZIP) proteins. The encoded transcription factor regulates genes which contain antioxidant response elements (ARE) in their promoters; many of these genes encode proteins involved in response to injury and inflammation which includes the production of free radicals. Multiple transcript variants encoding different isoforms have been characterized for this gene. [provided by RefSeq, Sep 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 26, 2024The c.1085G>A (p.G362D) alteration is located in exon 10 (coding exon 10) of the HNRNPA3 gene. This alteration results from a G to A substitution at nucleotide position 1085, causing the glycine (G) at amino acid position 362 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
