Genes affected

DNAJC30 (HGNC:16410): (DnaJ heat shock protein family (Hsp40) member C30) This intronless gene encodes a member of the DNAJ molecular chaperone homology domain-containing protein family. This gene is deleted in Williams syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at 7q11.23. [provided by RefSeq, Jul 2008]

Feb 10, 2023

The c.374T>C (p.V125A) alteration is located in exon 1 (coding exon 1) of the DNAJC30 gene. This alteration results from a T to C substitution at nucleotide position 374, causing the valine (V) at amino acid position 125 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
