Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2024The c.1606C>T (p.R536C) alteration is located in exon 15 (coding exon 14) of the ASCC2 gene. This alteration results from a C to T substitution at nucleotide position 1606, causing the arginine (R) at amino acid position 536 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
