Variant 14-55424216-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_199047.3(TBPL2):c.898A>G(p.Met300Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000684 in 1,461,166 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. M300T) has been classified as Uncertain significance.

The c.994A>G (p.M332V) alteration is located in exon 6 (coding exon 6) of the TBPL2 gene. This alteration results from a A to G substitution at nucleotide position 994, causing the methionine (M) at amino acid position 332 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
