Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.723C>A (p.N241K) alteration is located in exon 7 (coding exon 6) of the ABHD6 gene. This alteration results from a C to A substitution at nucleotide position 723, causing the asparagine (N) at amino acid position 241 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
