Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.718C>T (p.R240C) 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 718, causing the arginine (R) at amino acid position 240 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
