Genes affected
LAPTM4B (HGNC:13646): (lysosomal protein transmembrane 4 beta) Enables ceramide binding activity; enzyme binding activity; and phosphatidylinositol bisphosphate binding activity. Involved in several processes, including negative regulation of macromolecule metabolic process; regulation of lysosomal membrane permeability; and regulation of lysosome organization. Located in several cellular components, including endosome; lysosomal membrane; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.121G>A (p.G41S) alteration is located in exon 1 (coding exon 1) of the LAPTM4B gene. This alteration results from a G to A substitution at nucleotide position 121, causing the glycine (G) at amino acid position 41 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
