Genes affected
DNAJB1 (HGNC:5270): (DnaJ heat shock protein family (Hsp40) member B1) This gene encodes a member of the DnaJ or Hsp40 (heat shock protein 40 kD) family of proteins. 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. The encoded protein is a molecular chaperone that stimulates the ATPase activity of Hsp70 heat-shock proteins in order to promote protein folding and prevent misfolded protein aggregation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2024The c.734A>G (p.N245S) alteration is located in exon 2 (coding exon 2) of the DNAJB1 gene. This alteration results from a A to G substitution at nucleotide position 734, causing the asparagine (N) at amino acid position 245 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
