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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2022The c.59C>T (p.A20V) alteration is located in exon 1 (coding exon 1) of the DNAJC30 gene. This alteration results from a C to T substitution at nucleotide position 59, causing the alanine (A) at amino acid position 20 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
