Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 05, 2024The c.586G>A (p.A196T) alteration is located in exon 6 (coding exon 5) of the ABHD6 gene. This alteration results from a G to A substitution at nucleotide position 586, causing the alanine (A) at amino acid position 196 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
