Ambry Genetics RCV003169546 SCV003906025 uncertain significance Inborn genetic diseases 2023-02-27 criteria provided, single submitter clinical testing The c.1724G>A (p.R575H) alteration is located in exon 11 (coding exon 11) of the SYNGAP1 gene. This alteration results from a G to A substitution at nucleotide position 1724, causing the arginine (R) at amino acid position 575 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
PreventionGenetics, part of Exact Sciences RCV004740668 SCV005354510 uncertain significance SYNGAP1-related disorder 2024-06-03 no assertion criteria provided clinical testing The SYNGAP1 c.1724G>A variant is predicted to result in the amino acid substitution p.Arg575His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0042% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
