Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.1661C>T (p.P554L) alteration is located in exon 15 (coding exon 15) of the LRRC7 gene. This alteration results from a C to T substitution at nucleotide position 1661, causing the proline (P) at amino acid position 554 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
