Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV003993885 SCV004813964 uncertain significance not specified 2024-02-28 criteria provided, single submitter clinical testing Variant summary: SPG7 c.220G>A (p.Gly74Arg) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0001 in 251020 control chromosomes. To our knowledge, no occurrence of c.220G>A in individuals affected with Hereditary Spastic Paraplegia 7 and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 215213). Based on the evidence outlined above, the variant was classified as uncertain significance.
