Variant 20-56468722-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong

The ENST00000357348.10(RTF2):c.25C>A(p.Pro9Thr) variant causes a missense change. The variant allele was found at a frequency of 0.000000696 in 1,437,066 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. P9L) has been classified as Uncertain significance.

The c.25C>A (p.P9T) alteration is located in exon 1 (coding exon 1) of the RTFDC1 gene. This alteration results from a C to A substitution at nucleotide position 25, causing the proline (P) at amino acid position 9 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
