Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2024The c.666C>G (p.F222L) alteration is located in exon 9 (coding exon 9) of the MIOX gene. This alteration results from a C to G substitution at nucleotide position 666, causing the phenylalanine (F) at amino acid position 222 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
