Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2021The c.49C>T (p.R17W) alteration is located in exon 2 (coding exon 1) of the LRRC3 gene. This alteration results from a C to T substitution at nucleotide position 49, causing the arginine (R) at amino acid position 17 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
