Genes affected

LANCL2 (HGNC:6509): (LanC like glutathione S-transferase 2) Enables phosphatidylinositol-3-phosphate binding activity; phosphatidylinositol-4-phosphate binding activity; and phosphatidylinositol-5-phosphate binding activity. Involved in negative regulation of transcription, DNA-templated and positive regulation of abscisic acid-activated signaling pathway. Located in several cellular components, including cortical actin cytoskeleton; cytosol; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.548G>T (p.R183I) alteration is located in exon 4 (coding exon 4) of the LANCL2 gene. This alteration results from a G to T substitution at nucleotide position 548, causing the arginine (R) at amino acid position 183 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
