Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 16, 2022The c.26C>T (p.P9L) alteration is located in exon 2 (coding exon 1) of the ASPHD2 gene. This alteration results from a C to T substitution at nucleotide position 26, causing the proline (P) at amino acid position 9 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
