Genes affected

LYST (HGNC:1968): (lysosomal trafficking regulator) This gene encodes a protein that regulates intracellular protein trafficking in endosomes, and may be involved in pigmentation. Mutations in this gene are associated with Chediak-Higashi syndrome, a lysosomal storage disorder. Alternative splicing results in multiple transcript variants, though the full-length nature of some of these variants has not been determined. [provided by RefSeq, Apr 2013]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.006029457).

BP6

Variant 1-235788841-G-A is Benign according to our data. Variant chr1-235788841-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 702188.

BP7

Synonymous conserved (PhyloP=0.086 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00103 (157/152112) while in subpopulation AFR AF = 0.00357 (148/41496). AF 95% confidence interval is 0.0031. There are 0 homozygotes in GnomAd4. There are 70 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
