Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 01, 2022The c.997G>A (p.A333T) alteration is located in exon 8 (coding exon 8) of the LRP2BP gene. This alteration results from a G to A substitution at nucleotide position 997, causing the alanine (A) at amino acid position 333 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
