Submissions by phenotype
not specified Uncertain:1
The c.748C>G (p.L250V) alteration is located in exon 7 (coding exon 6) of the TOMM40 gene. This alteration results from a C to G substitution at nucleotide position 748, causing the leucine (L) at amino acid position 250 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
