Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2024The c.487C>T (p.L163F) alteration is located in exon 6 (coding exon 6) of the MTG1 gene. This alteration results from a C to T substitution at nucleotide position 487, causing the leucine (L) at amino acid position 163 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
