Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.1553A>C (p.E518A) alteration is located in exon 5 (coding exon 4) of the LRRN4 gene. This alteration results from a A to C substitution at nucleotide position 1553, causing the glutamic acid (E) at amino acid position 518 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
