Variant summary

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

The NM_002348.4(LY9):c.271C>T(p.Arg91Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000477 in 1,614,166 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. R91H) has been classified as Likely benign.

Ambry Genetics

Feb 05, 2024

The c.271C>T (p.R91C) alteration is located in exon 2 (coding exon 2) of the LY9 gene. This alteration results from a C to T substitution at nucleotide position 271, causing the arginine (R) at amino acid position 91 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
