Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.796C>T (p.L266F) alteration is located in exon 7 (coding exon 6) of the LRRC23 gene. This alteration results from a C to T substitution at nucleotide position 796, causing the leucine (L) at amino acid position 266 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
