Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.1342C>T (p.R448W) alteration is located in exon 2 (coding exon 2) of the ABHD15 gene. This alteration results from a C to T substitution at nucleotide position 1342, causing the arginine (R) at amino acid position 448 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
