Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2024The c.947G>A (p.R316Q) alteration is located in exon 17 (coding exon 13) of the LRMP gene. This alteration results from a G to A substitution at nucleotide position 947, causing the arginine (R) at amino acid position 316 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
