Labcorp Genetics (formerly Invitae), Labcorp	RCV000636835	SCV000758276	uncertain significance	Amelocerebrohypohidrotic syndrome	2022-05-04	criteria provided, single submitter	clinical testing	This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 130 of the ROGDI protein (p.Arg130Gln). This variant is present in population databases (rs374603311, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with ROGDI-related conditions. ClinVar contains an entry for this variant (Variation ID: 530798). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Illumina Laboratory Services, Illumina	RCV000636835	SCV001274645	uncertain significance	Amelocerebrohypohidrotic syndrome	2018-01-13	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
Ambry Genetics	RCV004025482	SCV005013629	uncertain significance	Inborn genetic diseases	2023-10-13	criteria provided, single submitter	clinical testing	The c.389G>A (p.R130Q) alteration is located in exon 6 (coding exon 6) of the ROGDI gene. This alteration results from a G to A substitution at nucleotide position 389, causing the arginine (R) at amino acid position 130 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
