Variant 8-144520575-C-T details in Genebe, Genetics Data Aggregator

Variant summary

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

The ENST00000292524.6(LRRC14):c.667C>T(p.Arg223Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000206 in 1,600,298 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. R223H) has been classified as Uncertain significance.

Ambry Genetics

Dec 27, 2023

The c.667C>T (p.R223C) alteration is located in exon 3 (coding exon 2) of the LRRC14 gene. This alteration results from a C to T substitution at nucleotide position 667, causing the arginine (R) at amino acid position 223 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
