Genes affected

AQR (HGNC:29513): (aquarius intron-binding spliceosomal factor) Enables 3'-5' RNA helicase activity and single-stranded RNA binding activity. Involved in mRNA splicing, via spliceosome. Located in nucleoplasm. Part of U2-type catalytic step 2 spliceosome. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, AQR
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.954

The c.2483G>T (p.G828V) alteration is located in exon 23 (coding exon 23) of the AQR gene. This alteration results from a G to T substitution at nucleotide position 2483, causing the glycine (G) at amino acid position 828 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
