Genes affected

MARVELD3 (HGNC:30525): (MARVEL domain containing 3) Enables mitogen-activated protein kinase kinase kinase binding activity. Involved in bicellular tight junction assembly. Acts upstream of or within several processes, including negative regulation of JNK cascade; negative regulation of epithelial cell migration; and negative regulation of epithelial cell proliferation. Located in bicellular tight junction and cytoplasmic vesicle. [provided by Alliance of Genome Resources, Apr 2022]

The c.145G>T (p.G49W) alteration is located in exon 1 (coding exon 1) of the MARVELD3 gene. This alteration results from a G to T substitution at nucleotide position 145, causing the glycine (G) at amino acid position 49 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
