Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2022The c.107T>G (p.V36G) alteration is located in exon 1 (coding exon 1) of the LACTB2 gene. This alteration results from a T to G substitution at nucleotide position 107, causing the valine (V) at amino acid position 36 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
