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=0.26751482).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000329 (50/152038) while in subpopulation NFE AF= 0.000647 (44/68038). AF 95% confidence interval is 0.000494. There are 0 homozygotes in gnomad4. There are 20 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 50 AD gene.

The HSPA9 c.1426G>A variant is predicted to result in the amino acid substitution p.Ala476Thr. This variant was reported in an individual with sporadic Parkinson disease (Burbulla et al. 2010. PubMed ID: 20817635). This variant is reported in 0.080% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/5-137894331-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
