Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 04, 2024The c.596T>C (p.V199A) alteration is located in exon 3 (coding exon 3) of the HSD17B2 gene. This alteration results from a T to C substitution at nucleotide position 596, causing the valine (V) at amino acid position 199 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
