Genes affected

DACT1 (HGNC:17748): (dishevelled binding antagonist of beta catenin 1) The protein encoded by this gene belongs to the dapper family, characterized by the presence of PDZ-binding motif at the C-terminus. It interacts with, and positively regulates dishevelled-mediated signaling pathways during development. Depletion of this mRNA from xenopus embryos resulted in loss of notochord and head structures, and mice lacking this gene died shortly after birth from severe posterior malformations. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012]

LINC01500 (HGNC:51166): (long intergenic non-protein coding RNA 1500)

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0032674968).
• BP6: Variant 14-58646712-G-A is Benign according to our data. Variant chr14-58646712-G-A is described in ClinVar as [Benign]. Clinvar id is 1257885.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.374 is higher than 0.05.
