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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BP6
Variant 17-6695776-G-T is Benign according to our data. Variant chr17-6695776-G-T is described in ClinVar as Likely_benign. ClinVar VariationId is 385284.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-4.94 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000015 (22/1461884) while in subpopulation MID AF = 0.00312 (18/5768). AF 95% confidence interval is 0.00202. There are 0 homozygotes in GnomAdExome4. There are 10 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
