Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.695C>G (p.S232C) alteration is located in exon 5 (coding exon 5) of the FAM173A gene. This alteration results from a C to G substitution at nucleotide position 695, causing the serine (S) at amino acid position 232 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
