Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 2P and 3B. PM2BP4_ModerateBP7
The NM_000081.4(LYST):c.8151T>C(p.Ile2717=) variant causes a splice region, synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000879 in 1,387,256 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★★).

Chédiak-Higashi syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 25, 2022 | This sequence change affects codon 2717 of the LYST mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the LYST protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs201045270, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with LYST-related conditions. ClinVar contains an entry for this variant (Variation ID: 211413). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
