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.

The c.1324A>G (p.T442A) alteration is located in exon 18 (coding exon 17) of the VIPAS39 gene. This alteration results from a A to G substitution at nucleotide position 1324, causing the threonine (T) at amino acid position 442 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
