Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2024The c.664C>T (p.R222W) alteration is located in exon 1 (coding exon 1) of the ASPHD1 gene. This alteration results from a C to T substitution at nucleotide position 664, causing the arginine (R) at amino acid position 222 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
