Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. BS1PP3

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.1069G>A (p.Ala357Thr) variant in the SLC26A4 gene is 0.46% for African/African American chromosomes by gnomAD v4.1.0 (489/1613848 with 95% CI), which is a high enough frequency to be classified as likely benign based on the thresholds defined by the ClinGen Hearing Loss Expert Panel (HL VCEP) for autosomal recessive hearing loss variants (BS1). The REVEL computational prediction analysis tool produced a score of 0.849, which is above the threshold necessary to apply PP3. The HL VCEP allows classification of variants as likely benign with only BS1 if no other criteria are in conflict. The HL EP reviewed the conflicting evidence (PP3) and felt it did not override the Likely Benign classification in​ this case as computational scores are error prone, especially when predicting pathogenicity. In summary, the HL VCEP classified this variant as likely benign. (BS1, PP3; Clingen Hearing Loss VCEP Specifications Version 2; 02/19/2025).

Genes affected
SLC26A4 (HGNC:8818): (solute carrier family 26 member 4) Mutations in this gene are associated with Pendred syndrome, the most common form of syndromic deafness, an autosomal-recessive disease. It is highly homologous to the SLC26A3 gene; they have similar genomic structures and this gene is located 3' of the SLC26A3 gene. The encoded protein has homology to sulfate transporters.
