Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_StrongBP6BS2_Supporting
The NM_024426.6(WT1):c.662-6C>A variant causes a splice region, splice polypyrimidine tract, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000274 in 1,612,124 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).
WT1 (HGNC:12796): (WT1 transcription factor) This gene encodes a transcription factor that contains four zinc-finger motifs at the C-terminus and a proline/glutamine-rich DNA-binding domain at the N-terminus. It has an essential role in the normal development of the urogenital system, and it is mutated in a small subset of patients with Wilms tumor. This gene exhibits complex tissue-specific and polymorphic imprinting pattern, with biallelic, and monoallelic expression from the maternal and paternal alleles in different tissues. Multiple transcript variants have been described. In several variants, there is evidence for the use of a non-AUG (CUG) translation initiation codon upstream of, and in-frame with the first AUG. Authors of PMID:7926762 also provide evidence that WT1 mRNA undergoes RNA editing in human and rat, and that this process is tissue-restricted and developmentally regulated.

Verdict is Likely_benign. Variant got -6 ACMG points.
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.74).
BP6
Variant 11-32428625-G-T is Benign according to our data. Variant chr11-32428625-G-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 241486.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=5, Uncertain_significance=2}. Variant chr11-32428625-G-T is described in Lovd as [Likely_benign].
BS2
High AC in GnomAd4 at 48 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
