Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2021The c.301G>A (p.A101T) alteration is located in exon 3 (coding exon 2) of the LRRC31 gene. This alteration results from a G to A substitution at nucleotide position 301, causing the alanine (A) at amino acid position 101 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
