Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 30, 2023The c.1349C>T (p.T450M) alteration is located in exon 3 (coding exon 3) of the LARP6 gene. This alteration results from a C to T substitution at nucleotide position 1349, causing the threonine (T) at amino acid position 450 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
