Genes affected

DNAJB12 (HGNC:14891): (DnaJ heat shock protein family (Hsp40) member B12) DNAJB12 belongs to the evolutionarily conserved DNAJ/HSP40 family of proteins, which regulate molecular chaperone activity by stimulating ATPase activity. DNAJ proteins may have up to 3 distinct domains: a conserved 70-amino acid J domain, usually at the N terminus; a glycine/phenylalanine (G/F)-rich region; and a cysteine-rich domain containing 4 motifs resembling a zinc finger domain (Ohtsuka and Hata, 2000 [PubMed 11147971]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Dec 23, 2022

The c.290C>T (p.P97L) alteration is located in exon 2 (coding exon 2) of the DNAJB12 gene. This alteration results from a C to T substitution at nucleotide position 290, causing the proline (P) at amino acid position 97 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
