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

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP3
MetaRNN computational evidence supports a deleterious effect, 0.792
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000342 (50/1461892) while in subpopulation NFE AF= 0.000045 (50/1112012). AF 95% confidence interval is 0.0000346. There are 0 homozygotes in gnomad4_exome. There are 29 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 50 AD gene.

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.3947A>G (p.E1316G) alteration is located in exon 3 (coding exon 3) of the SALL1 gene. This alteration results from a A to G substitution at nucleotide position 3947, causing the glutamic acid (E) at amino acid position 1316 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
