Genes affected

SIX5 (HGNC:10891): (SIX homeobox 5) The protein encoded by this gene is a homeodomain-containing transcription factor that appears to function in the regulation of organogenesis. This gene is located downstream of the dystrophia myotonica-protein kinase gene. Mutations in this gene are a cause of branchiootorenal syndrome type 2. [provided by RefSeq, Jul 2009]

DM1-AS (HGNC:53125): (DM1 locus antisense RNA)

(HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.13204035).
• BP6: Variant 19-45768053-C-A is Benign according to our data. Variant chr19-45768053-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 1606562.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=1.55 with no splicing effect.
