not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.377C>T (p.S126F) alteration is located in exon 11 (coding exon 7) of the LRMP gene. This alteration results from a C to T substitution at nucleotide position 377, causing the serine (S) at amino acid position 126 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
