Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2024The c.610G>C (p.D204H) alteration is located in exon 2 (coding exon 1) of the LRRC3 gene. This alteration results from a G to C substitution at nucleotide position 610, causing the aspartic acid (D) at amino acid position 204 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
