Genes affected

HSPA9 (HGNC:5244): (heat shock protein family A (Hsp70) member 9) This gene encodes a member of the heat shock protein 70 gene family. The encoded protein is primarily localized to the mitochondria but is also found in the endoplasmic reticulum, plasma membrane and cytoplasmic vesicles. This protein is a heat-shock cognate protein. This protein plays a role in cell proliferation, stress response and maintenance of the mitochondria. A pseudogene of this gene is found on chromosome 2.[provided by RefSeq, May 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.044263214).

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000328 (5/152326) while in subpopulation SAS AF= 0.000828 (4/4832). AF 95% confidence interval is 0.000282. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 5 AD gene.

The c.1721G>A (p.R574Q) alteration is located in exon 14 (coding exon 14) of the HSPA9 gene. This alteration results from a G to A substitution at nucleotide position 1721, causing the arginine (R) at amino acid position 574 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
