Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2023The c.307A>T (p.I103F) alteration is located in exon 2 (coding exon 1) of the LRRC3 gene. This alteration results from a A to T substitution at nucleotide position 307, causing the isoleucine (I) at amino acid position 103 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
