Variant chr15-81003034-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2BP4BS2

The NM_022566.3(TLNRD1):c.763G>A(p.Val255Met) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000357 in 1,399,238 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. V255L) has been classified as Uncertain significance.

Genes affected

TLNRD1 (HGNC:13519): (talin rod domain containing 1) This gene encodes a protein that is regulated by micro RNA MiR-574-3, and is thought to have an oncogenic function in human bladder cancer. A similar gene in mouse is located in a chromosomal region critical for differentiation of mesoderm, which affects embryo patterning and the formation of heart, muscle, blood, skeleton and the urogenital system. The mouse gene is expressed in early development, and in the adult. [provided by RefSeq, Nov 2016]

Aug 12, 2021

The c.763G>A (p.V255M) alteration is located in exon 1 (coding exon 1) of the MESDC1 gene. This alteration results from a G to A substitution at nucleotide position 763, causing the valine (V) at amino acid position 255 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
