Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.109T>C (p.W37R) alteration is located in exon 2 (coding exon 1) of the ASPHD2 gene. This alteration results from a T to C substitution at nucleotide position 109, causing the tryptophan (W) at amino acid position 37 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
