Variant 20-50593191-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_001290268.2(RIPOR3):c.2218C>T(p.Arg740Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000447 in 1,611,860 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. R740H) has been classified as Uncertain significance.

Ambry Genetics

Feb 28, 2024

The c.2206C>T (p.R736C) alteration is located in exon 18 (coding exon 17) of the FAM65C gene. This alteration results from a C to T substitution at nucleotide position 2206, causing the arginine (R) at amino acid position 736 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
