Neuberg Centre For Genomic Medicine, NCGM	RCV001843690	SCV004176696	uncertain significance	Renal tubular acidosis, distal, 4, with hemolytic anemia		criteria provided, single submitter	clinical testing	The missense c.713A>T p.Glu238Val variant in SLC4A1 gene has been reported previously in homozygous state in individuals affected with SLC4A1-related disorder. The p.Glu238Val variant is reported with an allele frequency of 0.2% in the gnomAD exomes database. This variant has been reported to the ClinVar database as Likely Benign / Benign / Likely Pathogenic. The amino acid change p.Glu238Val in SLC4A1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Glu at position 238 is changed to a Val changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as a Variant of Uncertain Significance VUS. In the absence of another reportable variant in SLC4A1 gene, the molecular diagnosis is not confirmed.
