Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.619G>T (p.V207L) alteration is located in exon 6 (coding exon 6) of the DECR1 gene. This alteration results from a G to T substitution at nucleotide position 619, causing the valine (V) at amino acid position 207 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Progressive encephalopathy with leukodystrophy due to DECR deficiency Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 12, 2021In 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 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: "Benign"; Align-GVGD: "Class C0"). This variant has been observed in an individual with an abnormal newborn screening result suggestive of DECR1-related disease (Invitae). This variant is present in population databases (rs774551643, ExAC 0.003%). This sequence change replaces valine with leucine at codon 207 of the DECR1 protein (p.Val207Leu). The valine residue is highly conserved and there is a small physicochemical difference between valine and leucine. -
