Genes affected

SLC26A5 (HGNC:9359): (solute carrier family 26 member 5) This gene encodes a member of the SLC26A/SulP transporter family. The protein functions as a molecular motor in motile outer hair cells (OHCs) of the cochlea, inducing changes in cell length that act to amplify sound levels. The transmembrane protein is an incomplete anion transporter, and does not allow anions to cross the cell membrane but instead undergoes a conformational change in response to changes in intracellular Cl- levels that results in a change in cell length. The protein functions at microsecond rates, which is several orders of magnitude faster than conventional molecular motor proteins. Mutations in this gene are potential candidates for causing neurosensory deafness. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Nov 2009]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP6: Variant 7-103420728-A-ATC is Benign according to our data. Variant chr7-103420728-A-ATC is described in ClinVar as [Likely_benign]. Clinvar id is 48338.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00278 (424/152316) while in subpopulation AFR AF= 0.00981 (408/41572). AF 95% confidence interval is 0.00903. There are 4 homozygotes in gnomad4. There are 194 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 3 AR gene
