Genes affected

SALL4 (HGNC:15924): (spalt like transcription factor 4) This gene encodes a zinc finger transcription factor thought to play a role in the development of abducens motor neurons. Defects in this gene are a cause of Duane-radial ray syndrome (DRRS). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0027288496).
• BP6: Variant 20-51790301-C-G is Benign according to our data. Variant chr20-51790301-C-G is described in ClinVar as [Benign]. Clinvar id is 287110.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0741 is higher than 0.05.
