Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.877C>T (p.L293F) alteration is located in exon 5 (coding exon 5) of the ANKRD33 gene. This alteration results from a C to T substitution at nucleotide position 877, causing the leucine (L) at amino acid position 293 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
