Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2021The c.155T>A (p.L52Q) alteration is located in exon 8 (coding exon 4) of the LRMP gene. This alteration results from a T to A substitution at nucleotide position 155, causing the leucine (L) at amino acid position 52 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
