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.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_000441.2

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 167 curated pathogenic missense variants (we use a threshold of 10). The gene has 19 curated benign missense variants. Trascript score misZ: -1.7621 (below the threshold of 3.09). GenCC associations: The gene is linked to autosomal recessive nonsyndromic hearing loss 4, Pendred syndrome, athyreosis, thyroid hypoplasia, hearing loss, autosomal recessive.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.919

Variant classified as Uncertain Significance - Favor Pathogenic. The p.Phe504Ser variant in SLC26A4 has been reported in the compound heterozygous state in one individual with clinical features of Pendred syndrome (Soh 2015) and was absent from large population studies. Computational prediction tools and conservation a nalyses suggest that this variant may impact the protein, though this informatio n is not predictive enough to determine pathogenicity. In summary, while there i s some suspicion for a pathogenic role, the clinical significance of this varian t is uncertain. ACMG/AMP Criteria applied: PM2; PM3; PP3. -
