Genes affected

PALLD (HGNC:17068): (palladin, cytoskeletal associated protein) This gene encodes a cytoskeletal protein that is required for organizing the actin cytoskeleton. The protein is a component of actin-containing microfilaments, and it is involved in the control of cell shape, adhesion, and contraction. Polymorphisms in this gene are associated with a susceptibility to pancreatic cancer type 1, and also with a risk for myocardial infarction. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

PALLD links:

CBR4 (HGNC:25891): (carbonyl reductase 4) Enables several functions, including 3-oxoacyl-[acyl-carrier-protein] reductase (NADPH) activity; NADPH binding activity; and NADPH dehydrogenase (quinone) activity. Involved in fatty acid biosynthetic process; glycoside metabolic process; and protein tetramerization. Located in mitochondrial matrix. Part of oxidoreductase complex.

Collection Method: clinical testing

The c.1468C>T (p.R490C) alteration is located in exon 9 (coding exon 8) of the PALLD gene. This alteration results from a C to T substitution at nucleotide position 1468, causing the arginine (R) at amino acid position 490 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Collection Method: clinical testing

This variant has not been reported in the literature in individuals with PALLD-related disease. This variant is present in population databases (rs151071844, ExAC 0.03%), and has an allele count higher than expected for a pathogenic variant (PMID: 28166811). This sequence change replaces arginine with cysteine at codon 490 of the PALLD protein (p.Arg490Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. -
