Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.62C>T (p.T21M) alteration is located in exon 1 (coding exon 1) of the LRRC30 gene. This alteration results from a C to T substitution at nucleotide position 62, causing the threonine (T) at amino acid position 21 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
