Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.16A>C (p.S6R) alteration is located in exon 5 (coding exon 1) of the LRMP gene. This alteration results from a A to C substitution at nucleotide position 16, causing the serine (S) at amino acid position 6 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
