Genes affected

DNAJA4 (HGNC:14885): (DnaJ heat shock protein family (Hsp40) member A4) Enables chaperone binding activity and unfolded protein binding activity. Involved in several processes, including negative regulation of endothelial cell migration; negative regulation of inclusion body assembly; and protein refolding. Located in cytosol and membrane.

DNAJA4 links:

SKIC8 (HGNC:30300): (SKI8 subunit of superkiller complex) WDR61 is a subunit of the human PAF and SKI complexes, which function in transcriptional regulation and are involved in events downstream of RNA synthesis, such as RNA surveillance (Zhu et al., 2005 [PubMed 16024656]).[supplied by OMIM, Mar 2008]

The c.1114C>G (p.L372V) alteration is located in exon 8 (coding exon 8) of the DNAJA4 gene. This alteration results from a C to G substitution at nucleotide position 1114, causing the leucine (L) at amino acid position 372 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
