Genes affected

SALL1 (HGNC:10524): (spalt like transcription factor 1) The protein encoded by this gene is a zinc finger transcriptional repressor and may be part of the NuRD histone deacetylase complex (HDAC). Defects in this gene are a cause of Townes-Brocks syndrome (TBS) as well as bronchio-oto-renal syndrome (BOR). Two transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.005468607).
• BP6: Variant 16-51141413-G-A is Benign according to our data. Variant chr16-51141413-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 282089.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr16-51141413-G-A is described in Lovd as [Benign]. Variant chr16-51141413-G-A is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000919 (140/152334) while in subpopulation EAS AF= 0.0224 (116/5178). AF 95% confidence interval is 0.0191. There are 1 homozygotes in gnomad4. There are 75 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAd at 140 AD gene.
