Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2022The c.1204C>T (p.R402W) alteration is located in exon 7 (coding exon 6) of the LRRIQ3 gene. This alteration results from a C to T substitution at nucleotide position 1204, causing the arginine (R) at amino acid position 402 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
