Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.992A>G (p.D331G) alteration is located in exon 9 (coding exon 8) of the ABHD6 gene. This alteration results from a A to G substitution at nucleotide position 992, causing the aspartic acid (D) at amino acid position 331 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
