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

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.37).
• BP6: Variant 5-138559873-C-T is Benign according to our data. Variant chr5-138559873-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 755721.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=1.61 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000782 (114/1457402) while in subpopulation SAS AF= 0.000755 (65/86144). AF 95% confidence interval is 0.000607. There are 1 homozygotes in gnomad4_exome. There are 79 alleles in male gnomad4_exome subpopulation. Median coverage is 29. This position pass quality control queck.
• BS2: High AC in GnomAdExome at 29 AD gene.
