Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2022The c.966A>G (p.I322M) alteration is located in exon 4 (coding exon 4) of the TEFM gene. This alteration results from a A to G substitution at nucleotide position 966, causing the isoleucine (I) at amino acid position 322 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
