Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.680C>T (p.T227M) alteration is located in exon 6 (coding exon 6) of the LRP2BP gene. This alteration results from a C to T substitution at nucleotide position 680, causing the threonine (T) at amino acid position 227 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
