Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.886C>T (p.R296C) alteration is located in exon 6 (coding exon 6) of the OLFM2 gene. This alteration results from a C to T substitution at nucleotide position 886, causing the arginine (R) at amino acid position 296 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
