Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.1781C>A (p.T594K) alteration is located in exon 5 (coding exon 4) of the LRRN4 gene. This alteration results from a C to A substitution at nucleotide position 1781, causing the threonine (T) at amino acid position 594 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
