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]

The c.187G>A (p.A63T) alteration is located in exon 1 (coding exon 1) of the DNAJC30 gene. This alteration results from a G to A substitution at nucleotide position 187, causing the alanine (A) at amino acid position 63 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
