Genes affected

VIPAS39 (HGNC:20347): (VPS33B interacting protein, apical-basolateral polarity regulator, spe-39 homolog) Involved in endosome to lysosome transport and intracellular protein transport. Acts upstream of or within collagen metabolic process and peptidyl-lysine hydroxylation. Located in Golgi apparatus and endosome. Implicated in arthrogryposis, renal dysfunction, and cholestasis 2.

Ambry Genetics

Feb 06, 2024

The c.1379G>A (p.R460H) alteration is located in exon 19 (coding exon 18) of the VIPAS39 gene. This alteration results from a G to A substitution at nucleotide position 1379, causing the arginine (R) at amino acid position 460 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
