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]

Ambry Genetics

Jul 12, 2023

The c.433G>T (p.V145F) alteration is located in exon 3 (coding exon 3) of the LANCL2 gene. This alteration results from a G to T substitution at nucleotide position 433, causing the valine (V) at amino acid position 145 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
