• DNAJB5 p.25

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP7

The NM_001349723.3(DNAJB5):​c.70_72delCGGinsAGA​(p.25) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

DNAJB5 (HGNC:14887): (DnaJ heat shock protein family (Hsp40) member B5) This gene encodes a member of the DNAJ heat shock protein 40 family of co-chaperone proteins. The encoded protein contains an N-terminal DNAJ domain and a C-terminal substrate binding domain but lacks the cysteine-rich domain found in other DNAJ family members. In mice, a multi-protein complex containing this protein, thioredoxin 1, and histone deacetylase 4, serves as a master negative regulator of cardiac hypertrophy. [provided by RefSeq, Mar 2017]

DNAJB5-DT (HGNC:49846): (DNAJB5 divergent transcript)

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• BP7: Synonymous conserved (PhyloP=2.54 with no splicing effect.
