Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 17, 2023The c.721G>T (p.A241S) alteration is located in exon 9 (coding exon 9) of the APOOL gene. This alteration results from a G to T substitution at nucleotide position 721, causing the alanine (A) at amino acid position 241 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
