Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2024The c.109G>A (p.G37S) alteration is located in exon 3 (coding exon 2) of the ASAH2B gene. This alteration results from a G to A substitution at nucleotide position 109, causing the glycine (G) at amino acid position 37 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
