Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.619C>T (p.R207C) alteration is located in exon 8 (coding exon 8) of the SRRM4 gene. This alteration results from a C to T substitution at nucleotide position 619, causing the arginine (R) at amino acid position 207 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
