Variant 1-156581962-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_001105669.4(TTC24):c.598G>A(p.Ala200Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000094 in 1,383,544 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. A200S) has been classified as Uncertain significance.

The c.598G>A (p.A200T) alteration is located in exon 2 (coding exon 1) of the TTC24 gene. This alteration results from a G to A substitution at nucleotide position 598, causing the alanine (A) at amino acid position 200 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
