Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 16, 2022The c.578T>C (p.I193T) alteration is located in exon 6 (coding exon 5) of the SRR gene. This alteration results from a T to C substitution at nucleotide position 578, causing the isoleucine (I) at amino acid position 193 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
