Genes affected
LACTB (HGNC:16468): (lactamase beta) This gene encodes a mitochondrially-localized protein that has sequence similarity to prokaryotic beta-lactamases. Many of the residues responsible for beta-lactamase activity are not conserved in this protein, suggesting it may have a different enzymatic function. Increased expression of the related mouse gene was found to be associated with obesity. Alternative splicing results in multiple transcript variants encoding different protein isoforms.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.1415C>T (p.T472M) alteration is located in exon 6 (coding exon 6) of the LACTB gene. This alteration results from a C to T substitution at nucleotide position 1415, causing the threonine (T) at amino acid position 472 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
