Genes affected

PALM (HGNC:8594): (paralemmin) This gene encodes a member of the paralemmin protein family. The product of this gene is a prenylated and palmitoylated phosphoprotein that associates with the cytoplasmic face of plasma membranes and is implicated in plasma membrane dynamics in neurons and other cell types. Several alternatively spliced transcript variants have been identified, but the full-length nature of only two transcript variants has been determined. [provided by RefSeq, Jul 2008]

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 154 of the PALM protein (p.Thr154Met). This variant is present in population databases (rs772962279, gnomAD 0.02%). This missense change has been observed in individual(s) with PALM-related conditions (PMID: 30542205). ClinVar contains an entry for this variant (Variation ID: 431725). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
