not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 02, 2024The c.847G>A (p.D283N) alteration is located in exon 8 (coding exon 7) of the LEKR1 gene. This alteration results from a G to A substitution at nucleotide position 847, causing the aspartic acid (D) at amino acid position 283 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
