Genes affected

HSPA2 (HGNC:5235): (heat shock protein family A (Hsp70) member 2) Enables disordered domain specific binding activity; enzyme binding activity; and unfolded protein binding activity. Involved in negative regulation of inclusion body assembly and protein refolding. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

HSPA2-AS1 (HGNC:55433): (HSPA2 and ZBTB1 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.835 is higher than 0.05.
