Genes affected

HSPA8 (HGNC:5241): (heat shock protein family A (Hsp70) member 8) This gene encodes a member of the heat shock protein 70 family, which contains both heat-inducible and constitutively expressed members. This protein belongs to the latter group, which are also referred to as heat-shock cognate proteins. It functions as a chaperone, and binds to nascent polypeptides to facilitate correct folding. It also functions as an ATPase in the disassembly of clathrin-coated vesicles during transport of membrane components through the cell. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

ACMG classification

Verdict is Benign. Variant got -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.62).
• BP6: Variant 11-123059519-T-C is Benign according to our data. Variant chr11-123059519-T-C is described in ClinVar as [Benign]. Clinvar id is 786217.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.409 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00765 (1165/152276) while in subpopulation AFR AF= 0.0256 (1064/41554). AF 95% confidence interval is 0.0243. There are 15 homozygotes in gnomad4. There are 544 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd at 1160 AD gene.
