Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.821G>T (p.C274F) alteration is located in exon 8 (coding exon 8) of the LRRC34 gene. This alteration results from a G to T substitution at nucleotide position 821, causing the cysteine (C) at amino acid position 274 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
