Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2

The ENST00000371542.3(LRRC26):c.850G>A(p.Gly284Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000074 in 1,500,266 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 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. G284D) has been classified as Uncertain significance.

Ambry Genetics

Oct 14, 2021

The c.850G>A (p.G284S) alteration is located in exon 2 (coding exon 2) of the LRRC26 gene. This alteration results from a G to A substitution at nucleotide position 850, causing the glycine (G) at amino acid position 284 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
