Ambry Genetics RCV000251075 SCV000319257 pathogenic Cardiovascular phenotype 2014-03-27 criteria provided, single submitter clinical testing The p.R231Q pathogenic mutation (also known as c.692G>A), located in coding exon 2 of the SLC2A10 gene in the endofacial loop between two transmembrane domains, results from a G to A substitution at nucleotide position 692. The arginine at codon 231 is replaced by glutamine. This amino acid position is highly conserved on sequence alignment. This alteration was originally reported in a Spanish family in trans with a frameshift mutation in three affected siblings (Callewaert BL et al. Hum Mutat. 2008;29(1):150-158). In another study, p.R231Q was reported in a Japanese patient in trans with a nonsense mutation (Takahashi Y et al. Am J Med Genet A. 2013;161A(4):856-859). Another alteration of the same codon, p.R231W (c.691C>T), was reported in trans with a frameshift mutation in an Italian family (Ritelli M et al. Orphanet J Rare Dis. 2009;4:20). Based on the supporting evidence, p.R231Q is interpreted as a disease-causing mutation.
Illumina Clinical Services Laboratory,Illumina RCV000185549 SCV000914960 uncertain significance Arterial tortuosity syndrome 2017-05-09 criteria provided, single submitter clinical testing The SLC2A10 c.692G>A (p.Arg231Gln) variant has been reported in two studies in which it is found in a total of two patients in a compound heterozygous state with either a deletion or a stop-gained variant as the second allele (Callewaert et al. 2008; Takahashi et al. 2013). Control data are unavailable for this variant, which is reported at a frequency of 0.0000145 in the total population of the Genome Aggregation Database. The evidence for this variant is limited. The c.692G>A (p.Arg231Gln) variant is therefore classified as a variant of unknown significance but suspicious for pathogenicity for arterial tortuosity syndrome. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.

Division of Human Genetics,Children's Hospital of Philadelphia RCV000185549 SCV000238431 likely pathogenic Arterial tortuosity syndrome 2015-04-01 no assertion criteria provided research This patient is a carrier of a heterozygous likely pathogenic variant in the SLC2A10 gene implicated in causing arterial tortuosity syndrome (MIM 208050). The SLC2A10 variant (c.692G>A) was identified in several patients and segregated in a family with marked carotid artery pulsations and dysmorphic features (Callewaert et al. 2008, PMID: 17935213; Takahashi e al. 2012, PMID: 23494979).
