Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.98C>T (p.P33L) alteration is located in exon 4 (coding exon 1) of the LRRC56 gene. This alteration results from a C to T substitution at nucleotide position 98, causing the proline (P) at amino acid position 33 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
