Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2023The c.376C>G (p.R126G) alteration is located in exon 4 (coding exon 3) of the LRRC23 gene. This alteration results from a C to G substitution at nucleotide position 376, causing the arginine (R) at amino acid position 126 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
