Genes affected
SLC13A5 (HGNC:23089): (solute carrier family 13 member 5) This gene encodes a protein belonging to the solute carrier family 13 group of proteins. This family member is a sodium-dependent citrate cotransporter that may regulate metabolic processes. Mutations in this gene cause early infantile epileptic encephalopathy 25. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.69).
BP6
Variant 17-6707022-G-T is Benign according to our data. Variant chr17-6707022-G-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 383664.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000906 (138/152304) while in subpopulation NFE AF = 0.00148 (101/68024). AF 95% confidence interval is 0.00125. There are 0 homozygotes in GnomAd4. There are 67 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 2 AR,AD gene
