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 -9 ACMG points.

• BP6: Variant 16-51136183-CAAG-C is Benign according to our data. Variant chr16-51136183-CAAG-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 319579.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00244 (371/152266) while in subpopulation NFE AF= 0.0039 (265/68012). AF 95% confidence interval is 0.00351. There are 0 homozygotes in gnomad4. There are 180 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 371 AD gene.
