Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 4P and 1B. PM1 PM2 BP4

The NM_058246.4(DNAJB6):c.179A>C(p.Lys60Thr) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K60R) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: DNAJB6 NM_058246.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.29

Genes affected

DNAJB6 (HGNC:14888): (DnaJ heat shock protein family (Hsp40) member B6) This gene encodes a member of the DNAJ protein family. DNAJ family members are characterized by a highly conserved amino acid stretch called the 'J-domain' and function as one of the two major classes of molecular chaperones involved in a wide range of cellular events, such as protein folding and oligomeric protein complex assembly. This family member may also play a role in polyglutamine aggregation in specific neurons. Alternative splicing of this gene results in multiple transcript variants; however, not all variants have been fully described. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM1: In a region_of_interest Interaction with HSP70 (size 144) in uniprot entity DNJB6_HUMAN there are 32 pathogenic changes around while only 4 benign (89%) in NM_058246.4
• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3039103).
