Variant 16-1350144-G-A details in Genebe, Genetics Data Aggregator

Variant summary

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

The ENST00000007390.3(TSR3):c.617C>T(p.Ala206Val) variant causes a missense change. The variant allele was found at a frequency of 0.0000247 in 1,460,030 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. A206P) has been classified as Uncertain significance.

Ambry Genetics

Feb 28, 2023

The c.617C>T (p.A206V) alteration is located in exon 4 (coding exon 4) of the TSR3 gene. This alteration results from a C to T substitution at nucleotide position 617, causing the alanine (A) at amino acid position 206 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
