Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.1030C>T (p.L344F) alteration is located in exon 9 (coding exon 8) of the LEKR1 gene. This alteration results from a C to T substitution at nucleotide position 1030, causing the leucine (L) at amino acid position 344 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
