| Ambry Genetics | RCV004957960 | SCV005494413 | uncertain significance | Inborn genetic diseases | 2024-10-22 | criteria provided, single submitter | clinical testing | The c.518T>C (p.L173P) alteration is located in exon 5 (coding exon 5) of the SDCCAG8 gene. This alteration results from a T to C substitution at nucleotide position 518, causing the leucine (L) at amino acid position 173 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

RCV001099445 | SCV001255900 | uncertain significance | Senior-Loken syndrome 7 | 2018-01-12 | 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. |

RCV000652118 | SCV000773986 | uncertain significance | Senior-Loken syndrome 7; Bardet-Biedl syndrome 16 | 2021-10-27 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, a(n) neutral and non-polar amino acid, with proline, a(n) neutral and non-polar amino acid, at codon 173 of the SDCCAG8 protein (p.Leu173Pro). This variant is present in population databases (rs541533278, gnomAD 0.01%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with SDCCAG8-related conditions. ClinVar contains an entry for this variant (Variation ID: 541793). 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: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. |

RCV004735720 | SCV005360264 | uncertain significance | SDCCAG8-related disorder | 2024-09-13 | no assertion criteria provided | clinical testing | The SDCCAG8 c.518T>C variant is predicted to result in the amino acid substitution p.Leu173Pro. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.012% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
