Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.671G>A (p.R224K) alteration is located in exon 2 (coding exon 2) of the LRRC38 gene. This alteration results from a G to A substitution at nucleotide position 671, causing the arginine (R) at amino acid position 224 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
