Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 14, 2024The c.1783C>T (p.R595C) alteration is located in exon 16 (coding exon 16) of the LRRC7 gene. This alteration results from a C to T substitution at nucleotide position 1783, causing the arginine (R) at amino acid position 595 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
