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 Likely_benign. Variant got -6 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.32745332).
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0000157 (23/1461072) while in subpopulation EAS AF= 0.000353 (14/39692). AF 95% confidence interval is 0.000213. There are 0 homozygotes in gnomad4_exome. There are 10 alleles in male gnomad4_exome subpopulation. Median coverage is 30. 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.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.1976G>A (p.R659Q) alteration is located in exon 17 (coding exon 17) of the HSPA9 gene. This alteration results from a G to A substitution at nucleotide position 1976, causing the arginine (R) at amino acid position 659 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
