Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2024The c.1171C>T (p.P391S) alteration is located in exon 4 (coding exon 3) of the ANKAR gene. This alteration results from a C to T substitution at nucleotide position 1171, causing the proline (P) at amino acid position 391 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
