Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2023The c.13A>G (p.S5G) alteration is located in exon 1 (coding exon 1) of the LRP2BP gene. This alteration results from a A to G substitution at nucleotide position 13, causing the serine (S) at amino acid position 5 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
