Baylor Genetics RCV001331064 SCV001522984 uncertain significance 2-aminoadipic 2-oxoadipic aciduria 2019-01-07 criteria provided, single submitter clinical testing This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868].
Invitae RCV001331064 SCV003261020 uncertain significance 2-aminoadipic 2-oxoadipic aciduria 2021-12-23 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 585057). This variant has not been reported in the literature in individuals affected with DHTKD1-related conditions. This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 916 of the DHTKD1 protein (p.Lys916Arg).
Ambry Genetics RCV002532896 SCV003581167 uncertain significance Inborn genetic diseases 2021-09-15 criteria provided, single submitter clinical testing The c.2747A>G (p.K916R) alteration is located in exon 17 (coding exon 17) of the DHTKD1 gene. This alteration results from a A to G substitution at nucleotide position 2747, causing the lysine (K) at amino acid position 916 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.

GenomeConnect - Brain Gene Registry RCV001331064 SCV004804598 not provided 2-aminoadipic 2-oxoadipic aciduria no assertion provided phenotyping only Variant classified as Uncertain significance and reported on 01-07-2019 by Baylor Genetics. Assertions are reported exactly as they appear on the patient provided laboratory report. GenomeConnect does not attempt to reinterpret the variant. The IDDRC-CTSA National Brain Gene Registry (BGR) is a study funded by the U.S. National Center for Advancing Translational Sciences (NCATS) and includes 13 Intellectual and Developmental Disability Research Center (IDDRC) institutions. The study is led by Principal Investigator Dr. Philip Payne from Washington University. The BGR is a data commons of gene variants paired with subject clinical information. This database helps scientists learn more about genetic changes and their impact on the brain and behavior. Participation in the Brain Gene Registry requires participation in GenomeConnect.
