Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_139319.3(SLC17A8):c.354+4G>C variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000103 in 1,461,674 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

Genes affected

SLC17A8 (HGNC:20151): (solute carrier family 17 member 8) This gene encodes a vesicular glutamate transporter. The encoded protein transports the neurotransmitter glutamate into synaptic vesicles before it is released into the synaptic cleft. Mutations in this gene are the cause of autosomal-dominant nonsyndromic type 25 deafness. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

Variant classified as Uncertain Significance - Favor Benign. The 354+4G>C varian t in SLC17A8 has not been previously reported in individuals with hearing loss o r in large population studies. This variant is located in the 5' splice region but not in the invariant (+1/2) positions of the splice site consensus sequence and computational tools do not suggest and impact to splicing. However, this inf ormation is not predictive enough to rule out pathogenicity. In summary, the cli nical significance of this variant cannot be determined with certainty; however based upon the computational data, we would lean towards a more likely benign ro le. -
