Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2023The c.859T>C (p.C287R) alteration is located in exon 8 (coding exon 8) of the LRRC34 gene. This alteration results from a T to C substitution at nucleotide position 859, causing the cysteine (C) at amino acid position 287 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
