Genes affected

SYTL2 (HGNC:15585): (synaptotagmin like 2) The protein encoded by this gene is a synaptotagmin-like protein (SLP) that belongs to a C2 domain-containing protein family. The SLP homology domain (SHD) of this protein has been shown to specifically bind the GTP-bound form of Ras-related protein Rab-27A (RAB27A). This protein plays a role in RAB27A-dependent vesicle trafficking and controls melanosome distribution in the cell periphery. Alternative splicing results in multiple transcript variants encoding distinct isoforms.[provided by RefSeq, Jun 2009]

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=0.008764625).
• BP6: Variant 11-85711173-C-G is Benign according to our data. Variant chr11-85711173-C-G is described in ClinVar as Benign. ClinVar VariationId is 714262.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High Homozygotes in GnomAdExome4 at 6 AR gene
