Variant 8-97644793-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_178812.4(MTDH):c.287C>T(p.Pro96Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000665 in 1,549,348 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P96T) has been classified as Uncertain significance.

Genes affected

MTDH (HGNC:29608): (metadherin) Enables NF-kappaB binding activity; double-stranded RNA binding activity; and transcription coactivator activity. Involved in several processes, including lipopolysaccharide-mediated signaling pathway; positive regulation of intracellular signal transduction; and regulation of transcription, DNA-templated. Located in endoplasmic reticulum; nuclear lumen; and perinuclear region of cytoplasm. Implicated in hepatocellular carcinoma. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Nov 03, 2022

The c.287C>T (p.P96L) alteration is located in exon 1 (coding exon 1) of the MTDH gene. This alteration results from a C to T substitution at nucleotide position 287, causing the proline (P) at amino acid position 96 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
