Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.226A>C (p.N76H) alteration is located in exon 4 (coding exon 4) of the LRRC46 gene. This alteration results from a A to C substitution at nucleotide position 226, causing the asparagine (N) at amino acid position 76 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
