Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 1P and 0B. PP2

The NM_000081.4(LYST):c.4108C>T(p.Pro1370Ser) variant causes a missense change. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P1370A) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: LYST NM_000081.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 5.62

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

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PP2: Missense variant where missense usually causes diseases, LYST
