Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 18, 2022The c.4198C>T (p.R1400C) alteration is located in exon 19 (coding exon 19) of the CASKIN1 gene. This alteration results from a C to T substitution at nucleotide position 4198, causing the arginine (R) at amino acid position 1400 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
