Variant 17-39944481-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001195545.2(LRRC3C):c.575G>A(p.Arg192Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000155 in 1,487,326 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/20 in silico tools predict 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. R192L) has been classified as Uncertain significance.

The c.575G>A (p.R192Q) alteration is located in exon 2 (coding exon 2) of the LRRC3C gene. This alteration results from a G to A substitution at nucleotide position 575, causing the arginine (R) at amino acid position 192 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
