Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2023The c.395A>G (p.Y132C) alteration is located in exon 4 (coding exon 4) of the LRRC34 gene. This alteration results from a A to G substitution at nucleotide position 395, causing the tyrosine (Y) at amino acid position 132 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
