Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2022The c.955G>C (p.E319Q) alteration is located in exon 6 (coding exon 5) of the ABHD17A gene. This alteration results from a G to C substitution at nucleotide position 955, causing the glutamic acid (E) at amino acid position 319 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
