Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.436C>T (p.R146C) alteration is located in exon 6 (coding exon 5) of the SCML1 gene. This alteration results from a C to T substitution at nucleotide position 436, causing the arginine (R) at amino acid position 146 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
