Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2022The c.532C>T (p.R178C) alteration is located in exon 4 (coding exon 4) of the MYBPH gene. This alteration results from a C to T substitution at nucleotide position 532, causing the arginine (R) at amino acid position 178 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
